An account exists for one reason: to hold and revoke API keys. The inbox needs no account, and signing in gives nobody access to anyone's mail.
There is no email on file, so a forgotten password cannot be reset. Store it somewhere safe.
Signed in as
Addresses you created while signed in. They disappear here the moment they expire or you delete them. Being signed in lets you open them without the original token.

A key raises your rate limit. It does not grant access to any inbox — that still needs the inbox token. See the API docs.
