About Autofill security in 1Password for Android

Learn how 1Password protects your data when you use Autofill on your Android device.

When you turn on Autofill on your Android device, you can save logins and sign in to apps and websites without opening the 1Password app. Because you can save and sign in with your items so easily, you can create strong, unique passwords and passkeys for more apps and services than you otherwise might have, which means you can be more secure in more places.

Your secrets are safe in 1Password

1Password encrypts all your information, and using Autofill with 1Password doesn’t undermine the security of 1Password.

If you turn on Show filling suggestions, you can preview logins for a website or app without unlocking 1Password. To suggest logins, 1Password needs to store the account identifiers, vault identifiers, and item UUIDs in plaintext. It also stores encrypted item titles, domain names, app identifiers, and usernames, which it only decrypts to provide a preview. This metadata is stored in the 1Password app sandbox on your device, and no other apps can access it.

You are always in control

Filling suggestions are turned off by default. To turn them on, go to Settings > Autofill.

To sign in to an account using Autofill or filling suggestions, you must unlock 1Password and choose an item. As always, 1Password will only fill your credentials after you choose to fill them.

Protect yourself when using Autofill

If you turn on filling suggestions, guard your device passcode closely. Anyone who knows it can find out which websites and apps you have logins for, including your usernames for those logins.
