Only continue if you just clicked "Sign in with .key" on . The signature works only for that site and expires in 5 minutes.

1 · Load the key that owns your name

2 · Pick the name to sign in with

How it works

• The site sends you here with a one-time code. Your browser signs {name, address, site, code, time} with your key, using the standard Bitcoin BSV signed-message format (BSM).
• You go back to the site with that signature. It recovers the address from the signature and checks that the address owns the name on Bitcoin BSV.
• Your key is never sent anywhere. Close the tab and it's gone from memory.
• Sell or transfer the name and the old key can no longer sign in with it. The name, not a password database, is the account.

For developers: the zero-dependency checker and protocol notes are in BSVKey on GitHub as @bsvkey/keyauth. No name yet? Get one before yours is taken.
