那么，您忘记了您的智能手机密码(smartphone passcode)并且被锁定在您的设备之外？不用担心，这种情况发生的频率比您想象的要多。
您可以通过多种方式锁定智能手机。也许您在杂乱无章的地方发现了一部旧手机，并在尝试登录时意识到您忘记了密码。也许您习惯于在智能手机上使用指纹扫描仪(fingerprint scanner)或面部识别，而您不太记得备份密码(backup passcode)。
请记住，如果您重新启动设备，则需要输入手动密码才能继续使用您的生物识别选项。也许您最近出于安全原因更新了密码，但还没有完全记住它。
无论出于何种原因，我们都会让您重新登录智能手机。您可以采用多种方法。在下面查看您的选择。
(Erase Device)使用 Google“查找我的设备”擦除设备
请注意(Please note)此选项，删除设备上的所有信息并将其设置回出厂设置，就像首次购买时一样。如果您没有备份设备上的信息，这是一个
棘手的选项，但它是返回锁定设备的有效方法。(touchy option)
要使用此方法，您的设备还需要登录到您的Google 帐户(Google account)。如果是，请通过计算机、平板电脑或其他智能手机在网络浏览器上访问Google 查找我的设备页面。(Find My Device)如果该服务识别了您的手机，它将显示设备的信息，包括名称、定位时间、运营商和电池百分比(battery percentage)。
如果服务尚未(service hasn)找到您的设备，请单击刷新选项直到检测到它。如果您的设备已登录您的Google 帐户(Google account)，它最终会拿起该设备。
从这里，选择擦除设备(Erase
Device )并再次选择它以进行第二步。然后，您将被引导至Google 登录(Google login)页面，您必须在其中输入您的Google 帐户(Google account)
信息。这样做，该过程将开始。完成后，您将能够将(Once)智能手机设置为新设备并设置您可以记住的密码。
恢复出厂设置
与第一个选项一样，这将删除设备上的所有信息并将其恢复为出厂设置。但是，您无需访问Google 查找我的设备页面(Google Find My Device page)即可使用此选项。
要使用此选项，您必须将设备引导至恢复模式(Recovery mode)。执行此操作的标准方法是关闭设备电源，然后同时按住电源按钮(power button)和降低音量按钮。这将带您进入设备的引导加载程序。
功能可能因设备而异。某些设备可能需要您按住电源按钮(power button)和音量增大按钮。例如，较新的三星设备要求您按住(Newer Samsung)电源按钮(power button)、增大音量和Bixby 按钮(Bixby button)才能访问引导加载程序。
进入引导加载程序后，使用音量键导航到恢复模式(Recovery Mode)，然后按电源按钮(power button)进入。在恢复模式下(Recovery mode)，导航至Wipe data/factory reset。
按(Press)电源按钮(power button)确认该选项，您的设备将重新启动并擦除所有数据。完成后，您将能够使用您可以记住的密码将智能手机设置为新设备 。(Once)
请记住，较新的(mind newer) Android设备可能会要求您输入Google 帐户(Google account)的电子邮件和密码，然后才能继续恢复出厂设置。完成此操作后，重置应该会顺利进行。
安全模式选项
请注意(Please note)，此选项仅适用于您在智能手机上设置了自定义第三方(custom third-party)
锁定屏幕(lock screen)而不是股票锁定屏幕(stock lock screen)。此功能有效，因为安全模式会在您以这种方式登录时禁用所有第三方应用程序。
要启动到安全模式，请按智能手机上的电源按钮(power button)并长按关机选项(Power off option)。这将立即弹出一个提示，询问您是否要重新启动进入安全模式。选择确定(Select okay)，您的设备将重新启动。
进入安全模式后，第三方锁定屏幕(lock screen)将被禁用。从这里您可以清除密码或卸载应用程序。再次重新启动您的设备，您应该能够在不输入密码的情况下访问您的主屏幕。(home screen)然后，您可以根据需要在第三方应用程序上设置新密码，或通过现有的Android设置设置密码。
通过三星“查找我的手机”网站解锁
请注意(Please note)，如果您没有设置三星帐户(Samsung account)，您将无法使用此选项。总体而言，这是三星(Samsung)用户重置密码并重新获得智能手机访问权限的一种非常简单的方法。从计算机、平板电脑或其他智能手机通过网络浏览器访问
Samsung Find My Mobile页面。(Find My Mobile)
登录您的三星帐户(Samsung account)并选择锁定我的屏幕(Lock My Screen)选项。您将看到一个输入新PIN的选项。输入(Input)新的PIN 码(PIN code)并选择锁定(Lock)选项。
使用这个新的PIN登录您的设备，但请记住该代码是特定于Find My Mobile 服务(Find My Mobile service)的。您必须在设备的安全设置中更新为永久密码，才能保持对智能手机的访问。
访问 Android 调试桥 (ADB)
请注意(Please note)，这是一项高级功能，仅当您的智能手机已植根并且您已经在移动设备和计算机(device and computer)（Android SDK工具的一部分）上设置了Android 调试桥(Android Debug Bridge)( ADB ) 时才有效。(ADB)如果您对这些工具不是很熟悉，最好不要尝试此选项。
如果您的设备默认加密，您也可能会遇到此选项的问题。如果没有，通过ADB(ADB)重置密码是一种快速且近乎即插即用的方法(plug and play method)。它实质上删除了智能手机上的密码文件(password file)，允许在重新启动时直接登录到主屏幕(home screen)。
通过USB 数据(USB data)线将智能手机连接到Windows、Mac或Linux 计算机。(Linux computer)访问您的ADB 安装(ADB installation)目录并打开命令提示符窗口(command prompt window)。
输入命令 - adb shell rm /data/system/gesture.key - 然后按 Enter(– and press Enter)。如果您有Mac 或 Linux 计算机(Mac or Linux computer)，您可以打开终端窗口(Terminal window)，该窗口位于 Applications 文件夹的Utilities文件夹中。
完成此操作后，重新启动手机，您应该能够在没有密码的情况下访问设备。登录设备后，您必须更新为永久密码，因为此方法是一种临时措施。
“忘记模式”选项
此选项主要适用于运行Android 4.4或更早版本的旧手机，但如果您的设备满足要求，它是轻松访问手机的好选择。忘记图案功能是(Forgot Pattern feature)图案样式密码(pattern style passcode)独有的。
它将允许您在五次尝试失败后从锁定屏幕重置密码。(lock screen)在此之后，再次输入错误的密码(passcode one)，您将看到一条通知，让您可以选择使用安全问题(security question)解锁您的设备或等待 30 秒再试一次。如果您设置了安全问题(security question)或备份PIN并记住其详细信息，那么它也是此方法的一个选项。
如果没有，请选择忘记模式？(Forgot Pattern?)位于屏幕底部的选项，然后选择输入 Google 帐户详细信息(Enter Google account details)（如果该选项可用）。某些设备可能会直接进入下一步，您可以在其中输入与您的设备关联的Gmail 用户名和密码。(Gmail username and password)
选择登录(Sign In)，您将收到一封发送至该帐户的电子邮件，您可以在其中绘制新的图案密码(pattern passcode)，保存，然后使用密码再次登录您的设备。
紧急呼叫技巧
此选项适用于已加密并运行Android 5.0和5.1.1之间系统版本的旧手机。这是一个已在较旧的Android版本上修复的漏洞。但是，对于那些拥有正确软件(right software)的人来说，这是绕过锁定屏幕并访问(lock screen and gain access)智能手机的绝妙方法。
它实际上使锁屏(lock screen)用户界面崩溃，这使您可以绕过密码要求并登录(passcode requirement and log)到您的设备。请(Please)记住，此选项非常喜怒无常，不能保证有效。
在设备的锁定屏幕上选择紧急呼叫选项。(Emergency Call)一旦拨号器出现，输入 10 个星号。双击星号以突出显示字符。确保它们都突出显示，选择复制(Copy)选项。
将光标设置在第一组星号的末尾，然后将另一组星号粘贴到字段中。重复此复制(Copy)和粘贴(Paste)功能，直到该字段已满并且您无法再突出显示。
之后，返回锁定屏幕(lock screen)并打开相机。访问下拉通知菜单(notifications menu)，然后访问设置(Settings)图标。从这里，您将被要求输入密码。
再次，通过长按空格并选择(space and selecting)粘贴将您之前复制的星号粘贴到(Paste)密码字段(password field)中。重复此操作，直到锁定屏幕(lock screen)崩溃并将您的设备直接打开到其主屏幕(home screen)。
Can You Bypass the Android Lock Screen?
So, you’ve forgоtten your smartphone passcode and you’re locked out of your device? Not to worry, thіs hapрens way more oftеn than yoυ might think.
There are several ways you can get locked out of your smartphone. Perhaps you’ve discovered an old handset among some clutter and upon trying to log in, realize you’ve forgotten the passcode. Perhaps you’re used to using the fingerprint scanner or facial recognition on your smartphone and you don’t quite remember the backup passcode.
Keep in mind that if you restart your device, you will need to input a manual passcode before you can continue using your biometrics options. Perhaps you’ve recently updated your passcode for security reasons and haven’t quite memorized it yet.
Whatever the reason, we’re here to get you logged back into your
smartphone. There are several methods you can employ. Check out your options
below.
Erase Device with Google ‘Find My Device’
Please note this option with erase all information on the device
and set it back to factory settings like when it was first purchased. This is a
touchy option if you don’t have the information on your device backed up, but
it is an effective way to get back into a locked device.
To use this method, your device will also need to be logged into your Google account. If it is, access the Google Find My Device page on a web browser from a computer, tablet, or another smartphone. If the service has identified your phone, it will show the device’s information, including the name, how long ago it was located, the carrier, and the battery percentage.
If service hasn’t located your device, click the refresh option until it is detected. If your device is logged into your Google account, it will eventually pick up the device.
From here, select Erase
Device and select it again for the second step. You will then be directed
to a Google login page, where you will have to enter your Google account
information. Do this and the process will begin. Once complete, you will be
able to set up your smartphone as a new device and set up a passcode you can
remember.
Factory Reset
Like the first option, this will erase all information on the
device and take it back to factory settings. However, it is an option you can
employ without having to access the Google Find My Device page.
To use this option, you must boot the device into Recovery mode. The standard way to do this is by powering down a device and then holding the power button and the volume down button at the same time. This will take you to the device’s bootloader.
The function may vary depending on the device. Some devices may require you to hold the power button and the volume up button. Newer Samsung devices, for example, require you to hold the power button, volume up, and the Bixby button to access the bootloader.
Once at the bootloader, use the volume keys to navigate to Recovery Mode and press the power button to enter. In Recovery mode navigate to Wipe data/factory reset.
Press the power button to confirm the option and your device will restart and wipe all your data. Once complete, you will be able to set up your smartphone as a new device with a passcode you can remember.
Keep in mind newer Android devices may require you to input the email
and password for your Google account before to can proceed with a factory
reset. Once you do this, the reset should go smoothly.
Safe Mode Option
Please note this option only works if you have a custom third-party
lock screen set on your smartphone instead of the stock lock screen. This
function works because safe mode disables all third-party applications while
you’re logged in this way.
To boot into safe mode, press the power button on your smartphone and long press the Power off option. This will immediately
bring up a prompt asking if you want to reboot into safe mode. Select okay and
your device will reboot.
Once in safe mode, the third-party lock screen will be disabled. From here you can clear the password or uninstall the app. Restart your device again and you should be able to access your home screen without entering a passcode. You can then set a new password on your third-party app if you wish or set a password through the stock Android settings.
Unlock with Samsung ‘Find My
Mobile’ website
Please note if you do not have a Samsung account set up, you
won’t be able to use this option. Overall, this is a very easy way for Samsung users
to reset their passcode and regain access to their smartphone. Access the
Samsung Find My Mobile page on a web browser from a
computer, tablet, or another smartphone.
Sign in to your Samsung account and select the Lock My Screen option. You will see an option to enter a new PIN. Input a new PIN code and select the Lock option.
Use this new PIN to log into your device, but keep in mind the code is specific to the Find My Mobile service. You will have to update to a permanent passcode in your device’s security settings to maintain access to your smartphone.
Access Android Debug Bridge (ADB)
Please note this is an advanced function that only works if your smartphone is rooted and if you already have the Android Debug Bridge (ADB) set up on your mobile device and computer (part of the Android SDK tools). It is best to not attempt this option if you’re not very familiar with these tools.
You may also have issues with this option if your device is encrypted by default. If not, resetting your password through ADB is a quick and near plug and play method. It essentially deletes the password file on your smartphone, allowing login directly to the home screen upon restart.
Connect your smartphone to your Windows, Mac, or Linux computer via a USB data cable. Access your ADB installation directory and open a command prompt window.
Input the command – adb shell rm /data/system/gesture.key – and press Enter. If you have a Mac or Linux computer, you can open a Terminal window, which is found in the Utilities folder in the Applications folder.
Once you’ve done this, restart your phone and you should be able to access the device without a passcode. Once you’re logged into your device, you will have to update to a permanent passcode as this method is a temporary measure.
‘Forgot Pattern’ option
This option is mostly for older phones, running Android 4.4 or earlier, but if your device meets the requirement, it is a good option for easily gaining access to your phone. The Forgot Pattern feature is exclusive to the pattern style passcode.
It will allow you to reset your passcode from the lock screen after five failed attempts. After this, input an incorrect passcode one more time and you will see a notification that gives you the option to unlock your device with a security question or to wait 30 seconds to try again. If you have a security question or a backup PIN set up and remember its details, that it also an option with this method.
If not, select the Forgot Pattern? option located at the bottom of the screen and then select Enter Google account details if the option is available. Some devices may go directly to the next step, where you can input the Gmail username and password associated with your device.
Select Sign In and you will receive an email to that account where you can draw a new pattern passcode, save it, and use the passcode to login to your device again.
Emergency Call trick
This option is for older phones that are encrypted and running system versions between Android 5.0 and 5.1.1. It was a vulnerability that has since been fixed on older Android versions. However, for those with the right software, it is a nifty way to bypass a lock screen and gain access to your smartphone.
It essentially crashes the lock screen user interface, which allows you to bypass the passcode requirement and log into your device. Please keep in mind this option is very temperamental and it isn’t guaranteed to work.
Select the Emergency Call option on your device’s lock screen. Once the dialer comes up input 10 asterisks. Double tap the asterisks to highlight the characters. Making sure that they are all highlighted, select the Copy option.
Set your cursor at the end of the first set of asterisks and paste another set in the field. Repeat this Copy and Paste function until the field is full and you can no longer highlight.
After this, go back to the lock screen and open the camera. Access your drop-down notifications menu and then the Settings icon. From here, you will be asked to input a password.
Once again, paste your previously copied asterisks into the password field by long pressing the space and selecting Paste. Repeat this action until the lock screen crashes and opens your device directly to its home screen.
