@canvas-js/chain-atp

The Bluesky/AT Protocol session signer prompts the user for an app password, and uses it to generate a new signed post on Bluesky, authenticating a new session. The posted authentication message is then immediately deleted.

It also handles verification of messages matching this authentication method.
