With the passkey-based end-to-end encryption, each browser you view reports on needs your encryption key once. A browser that doesn't have it yet shows Unlock this browser in the End-to-End Encryption section of the account page, and the same Unlock encrypted data dialog opens when you try to view an encrypted screenshot.

There are three ways to unlock. Try them in this order.

1. Your passkey

Click Unlock this browser (or Unlock with passkey in the dialog) and approve your device's prompt with your fingerprint, face or PIN. This works wherever your passkey is available, including a passkey synced by your password manager. If this browser doesn't have your passkey, click I don't have my passkey on this device to see the other ways.

2. Your backup code

Click Load backup code file and pick the file you downloaded when the code was created. Its name starts with the app name and recovery-code and ends with your email address and the date; if you have several, use the newest one. You can also click Type the code instead and type it. See your encryption backup code.

3. Another browser that already has your keys

Click Use another device. This browser shows a short pairing code and waits. Then, on a browser that is already unlocked:

1. Open Best Accountability and sign in. A message says a device is requesting your encryption keys. Choose Review. (You can also get there from the account page: Show Advanced, then Share encryption keys.)
2. Check that the code shown there matches the code on the requesting browser exactly, tick the box to confirm, and click Approve.

The requesting browser unlocks on its own, even if you closed its tab in the meantime; the request is kept for 24 hours, and Cancel request withdraws it.

After you unlock

The browser offers to add its own passkey so it can unlock on its own next time. We recommend accepting; see setting up and using your encryption passkey.

If you have lost your passkey, your backup code and every browser that holds your keys, see resetting the passkey-based encryption.
