如果您不喜欢填写耗时的表格，或者对需要您填写的应用程序感到沮丧，那么这里有一些好消息：由于自动填充(autofill)，您不必再这样做了。Autofill是Google推出的专用框架，用于管理自动填充服务(autofill service)与Android 设备(Android device)上的应用程序之间的通信。
该服务的工作原理很像密码管理器，它可以减轻忘记密码的压力，并使用您的数据在其他应用程序中填写信息。这改善了用户体验(user experience)，因为您将花费更少的时间填写表单字段，并最大限度地减少拼写错误，尤其是在使用移动设备时。
自动填充框架(autofill framework)由密码管理器、自动填充客户端或保存数据的应用程序等服务，以及提供一切协同工作的平台的Android 操作系统组成。(Android OS)
自动填充功能随 Android Oreo(Autofill came with Android Oreo) (8.0) 一起提供，作为旨在使Android设备运行更流畅、更快、更酷的底层改进之一。对于用户和开发人员来说，这是天赐之物，因为它可以更轻松地在Netflix 等(Netflix and others)受支持的应用程序中输入登录凭据。
最初，每当您登录受支持的应用程序时，Google 的自动填充服务(autofill service)就会出现并使用 Google 的密码管理服务(management service)来输入您的登录凭据。
但今天，它可以与LastPass、1Password 或 Dashlane等其他(LastPass, 1Password or Dashlane)密码管理器(password manager)应用程序一起使用，这些应用程序在Oreo之前拥有自己的系统，可以通过一些黑客攻击自动填写您的用户名和密码。这不再是必要的。
如果您安装了这些应用程序中的任何一个，当网页(web page)提示进行身份验证或打开应用程序时，系统会提示您安全并自动输入您的登录详细信息。
自动填充的另一个重要方面是，如果您有未在密码管理器(password manager)中使用过的新登录名，那么当您第一次这样做时，它应该会提示您将数据保存到您的默认管理器应用程序(default manager app)中。
如何在您的 Google 帐户中使用自动填充功能(How To Use Autofill With Your Google Account)
在注册几乎所有在线可用服务时，您的Google 帐户非常有用。(Google account)事实上，它可能是 Facebook 在这一领域的最大竞争对手，尽管还有其他服务仍然需要您注册一个帐户才能使用它们。
大多数在线服务为用户提供了使用他们的Facebook 或 Google 帐户(Facebook or Google account)注册和登录的首选选项。
每次您访问网站上的注册页面时，您的信息都会在您使用Google 帐户(Google account)注册时自动填写。这是因为 Chrome 的自动填充功能(autofill feature)可以将您的登录凭据保存到您的Google 帐户(Google account)。
借助Android 应用程序和设备(Android apps and devices)上现在提供的自动填充功能，您可以存储您对Netflix等在线服务的登录信息，Google会在您登录的任何(Google)Android 设备(Android device)上自动填充数据。
要为应用程序和您的Android 设备(Android device)启用Google 自动填充(Google autofill)功能，请执行以下步骤。
转到Android 设备上的设置。(Settings)
向下滚动并找到系统(System)或常规管理。(General Management.)
点击语言和时间(Language and Time )（这可能会或可能不会出现，具体取决于您的Android 版本(Android version)。如果不可用，请转到下一步）。
选择语言和输入法。(Language & Input.)
点击底部的高级设置(Advanced settings)部分（输入辅助(Input Assistance)）以展开列表（取决于您的Android 版本(Android version)）。
点击自动填充服务(Autofill service)。
接下来，点击Google将其选中（默认）。
选择使用 Google 自动填充。(Autofill with Google.)
返回自动填充服务。(Autofill Service. )点按您选择的Google 应用(Google app)旁边的设置。(Settings )如果它是您的默认自动填充服务(default autofill service)，您应该会收到一个提示，向您显示Google可以看到的信息类型。
单击“确定(OK)”进行确认。选择您要用于自动填充服务的默认电子邮件地址。(default email address)单击(Click) 继续。(Continue.)
(Test)通过打开应用程序并在出现提示时尝试登录来测试服务，以将您的凭据发送到您的Google 帐户(Google account)。
如何使用密码管理器自动填充(How To Use Autofill With a Password Manager)
内置浏览器(Built-in browser)密码管理器（如Chrome、Safari、Firefox或Opera 中的密码管理器）有助于(Opera help)节省时间并方便密码管理(password management convenient)。然而，它们提供了一种虚假的安全感，这种感觉是站不住脚的，尤其是当浏览器被破坏(browser breach)时。
使用单独的专用密码管理器(password manager)，您可以创建和保存更好、更强的密码，因为他们知道它们会比在浏览器中更安全。目前，支持Google 自动填充的(Google autofill)密码管理器(password manager)应用包括LastPass（Google 认证(Google-certified)）、Enpass、1Password、Keeper 和 Dashlane(Keeper and Dashlane)。
如果您想设置自动填充以使用您的密码管理器(password manager)，您需要先下载管理器应用程序(manager app)。如果您的Android 设备(Android device)中已有一个，请使用以下步骤设置自动填充服务。
下载并安装 Google 支持的密码管理器(password manager)。
转到Settings > System.点击语言和输入法。(Language & Input.)
点击高级(Advanced)部分将其展开。选择自动填充服务(Autofill service)并选择您的密码管理器(password manager)。如果它不在列表中，请点击添加服务。(Add Service.)
打开一个应用程序，并在出现提示时，点击使用 [密码管理器](with [password manager])自动填充(Autofill) 。例如，如果您的默认应用(default app)是LastPass，请点击使用LastPass自动填充(Autofill)。
使用密码或指纹(password or fingerprint )进行身份验证以确认操作。登录(Log)您想要的应用程序并使用它。
您现在可以使用Google 帐户(Google account)或密码管理器(password manager)使用自动填充功能来输入您的登录凭据。每当您在任何应用程序上点击登录时，您的(sign in)电子邮件地址(email address)都会作为建议出现，就像Chrome的登录字段中的自动填充一样。
但是，使用第三方应用程序(party apps)时，系统会提示您解锁密码管理器(password manager)并选择您的凭据，而无需离开登录屏幕。
Autofill: What It Is & How To Use It On Your Android Device
If you’re not a fan of filling out time-consuming forms, or get frustrated with apps that requіre you to, here’s some good nеws: you don’t have to anymore thanks to autofill. Autofill is a dedicated framework introduced by Google that manages communication between the autofill service and apps on your Android device.
The service works much like password managers, which take the stress out of forgetting passwords and fills out information in other apps using your data. This improves the user experience because you’ll spend less time filling in form fields, and minimize typos especially when using mobile devices.
The autofill framework is composed of the services such as password managers, autofill clients or apps that hold your data, and the Android OS that offers the platform on which everything works together.
Autofill came with Android Oreo (8.0) as one of the under-the-hood improvements designed to make Android devices run smoother, faster and cooler. For users and developers, it’s a godsend because it makes it easier to enter login credentials in supported apps like Netflix and others.
Initially, whenever you signed into a supported app, Google’s autofill service would appear and used Google’s password management service to enter your login credentials.
Today though, it works with other password manager apps like LastPass, 1Password or Dashlane, which prior to Oreo, had their own system of automatically filling in your usernames and passwords with a few hacks. This is no longer necessary.
If you have any of these apps installed, you’ll be prompted to securely and automatically enter your login details when a web page prompts for authentication, or when opening apps.
Another great aspect of autofill is if you have new logins that you’ve not used in your password manager, when you do so the first time, it should prompt you to save the data to your default manager app.
How To Use Autofill With Your Google Account
Your Google account is useful when signing up for almost every service available online. In fact, it’s probably Facebook’s biggest rival in this area, though there are other services that still require you to sign up for an account to use them.
Most online services give users the preferred option of signing up and logging in using their Facebook or Google account.
Each time you visit a sign up page on a website, your information is automatically filled in when you sign up using your Google account. This is made possible because of Chrome’s autofill feature that saves your login credentials to your Google account.
With autofill now available on Android apps and devices, you can store your logins for online services like Netflix, for example, and Google will autofill the data on any Android device you log in to.
In order to enable Google autofill for apps and your Android device, take the steps below.
Go to Settings on your Android device.
Scroll down and find System or General Management.
Tap Language and Time ( this may or may not appear depending on your Android version. If it isn’t available, go to the next step).
Select Language & Input.
Tap the Advanced settings section (Input Assistance) at the bottom to expand the list (depending on your Android version).
Tap Autofill service.
Next, tap Google to select it (as default).
Select Autofill with Google.
Go back to Autofill Service. Tap Settings next to the Google app you selected. You should get a prompt that shows you the kind of information Google can see if it’s your default autofill service.
Click OK to confirm. Select the default email address you want to use with autofill service. Click Continue.
Test the service by opening an app and trying to sign in when prompted, to send your credentials to your Google account.
How To Use Autofill With a Password Manager
Built-in browser password managers like those in Chrome, Safari, Firefox or Opera help save time and make password management convenient. However, they offer a false sense of security, which doesn’t hold up, especially when there’s a browser breach.
With a separate and dedicated password manager, you can create and keep better and stronger passwords, knowing they’ll be more secure than they would in your browser. Currently, the password manager apps that support Google autofill include LastPass (Google-certified), Enpass, 1Password, Keeper and Dashlane.
If you want to set up autofill to work with your password manager, you’ll need to download the manager app first. If you already have one in your Android device, use the steps below to set up autofill service.
Download and install a Google-supported password manager.
Go to Settings > System. Tap Language & Input.
Tap the Advanced section to expand it. Select Autofill service and choose your password manager. If it isn’t on the list, tap Add Service.
Open an app and when prompted, tap Autofill with [password manager]. For example, if your default app is LastPass, tap Autofill with LastPass.
Authenticate using a password or fingerprint to confirm the action. Log into the app you want and use it.
You can now use autofill to enter your login credentials using your Google account or your password manager. Whenever you tap sign in on any app, your email address will appear as a suggestion, much like autofill for Chrome in the signin field.
With third party apps, however, you’ll be prompted to unlock your password manager and choose your credentials without leaving the sign in screen.
