Sign in at noket.dev/login with the email address you want to use for the account. Verify the address when the console asks; models, API keys, and usage all belong to the account, so an abandoned address means losing access to them.
noket login takes you to the same place: it opens the authorization page in your browser and waits
for you to approve it. That approval needs an existing signed-in session, so sign in first if you have
not.
Invitations
If someone shares a model with you, you may receive an invitation link of the form
/invite/<token>. Open it while signed in. The token belongs to the invitation, not to your account,
and it stops working once used or revoked.
Sessions
The account page lists the sessions signed in to the console. Sign out of a session you no longer
recognise. Signing out of the console does not remove the token stored on a machine where you ran
noket login; use noket logout for that machine.
