Bring an identity here
This browser has no identity yet. If you already have one on another browser, you can either add this browser to it or recover it here.
Use a passkey
If you made one, your device already knows which identity it belongs to. Nothing to type.
The first adds this browser and leaves the others working. The second is for when you no longer trust one of them.
Add this browser
You still have your other browser and want to use both. Nothing is revoked. Open your identity page there — its address ends in your fingerprint — and put that fingerprint here.
Enter this on your other browser, under Devices:
Waiting to be approved… this page will take over as soon as it is.
Recover an identity
You lost the other browser, or think its key is in someone else's hands. This browser gets a new key and every earlier browser key is revoked.
