Enhanced security options in iOS 12 give you automatic password suggestions, a way to find and change weak passwords, auto-populate 2FA codes, and Siri integration. Most of them are for iCloud Keychain, but Apple has not forgotten the users of third-party password managers. In iOS 12, you can use 1Password, LastPass, and others with the AutoFill feature in websites and apps.
Although Apple now allows the use of AutoFill by third-party password managers, there are some limitations compared to Keychain. Probably the most disappointing difference is the AutoFill password creation tool. This new password generator is only available for iCloud Keychain and creates and stores only passwords for this manager. Maybe we'll see this feature with third-party password managers in iOS 1
Step 1: Enable AutoFill for your Password Manager
First, start your app settings. Select "Passwords and Accounts" and tap "AutoFill Passwords". If AutoFill Passwords is simply a togger and not a menu, it means that you have not set up a compatible third-party password manager on your iPhone. We recommend that you contact your password manager to see when he adds support.
Look in the AutoFill Passwords settings to populate your third-party manager or manager from the list below Fill From the section
In the remaining instructions below, we use 1Password (Beta) as an example. While most steps are the same for other supported password managers, some may only apply to 1Password.
Step 2: Authenticate with the Password Manager
Once you select your password manager from the list, you will need to authenticate yourself with Face ID, Touch ID, or the password of your iPhone. After approval, enable or disable notifications for your password manager in the following pop-up window. (What you choose is up to you.)
Next, you can set notifications on the clipboard to notify you. A password has been copied to your clipboard. You do not need to enable this, but to access this option again, you must first deselect your password manager from the setting in the previous step, and then run that configuration again.
Step 3: Use Your Third-Party Password Manager with AutoFill
If you've set up your password manager, you'll now see AutoFill suggestions for that account when prompted in Safari and in apps that feature this feature support.
In some cases, when you first open the iOS 12 sign-in page, you'll automatically be asked if you want to sign in to the site or app using your third-party password manager. Tap "Use" [your username] "Authenticate, and AutoFill will automatically enter the account information in the correct fields, then log in as normal.
If it is not as shown above, tap instead of the password field In the QuickType bar above the keyboard you will see the username of the account and the name of your password manager Tap the link, authenticate yourself and AutoFill will automatically enter the account information in the correct fields and then log in completely normal.  3. Find AutoFill for the right password manager
If you have your .type in the QuickType bar above If you do not see the preferred account and / or password manager, tap the far right button. Also, tap "Passwords" in the QuickType bar if no referral is displayed. Find and tap the correct password and manager in the list, or tap your password manager yourself, then authenticate yourself and tap the appropriate item on the following page. In both cases, your account and password will automatically be filled in where you need them.
