Signing in
Sign this copy of Oba in
Type /login in the Oba window and it brings you here with a code. On its own this page signs in nothing.
How long a sign in lasts
Thirty days. After that Oba reads one sentence to you and you sign in again. There is nothing to renew and nothing that renews itself.
If the digits do not arrive, or are refused
Wait a minute and ask again: one address is sent one code a minute. A code lasts an hour, and five wrong tries end it. Type the newest six digits you were sent.
Signing out
Type /logout in the Oba window. Oba hands the sign in back and the service forgets it, and only then does that copy of Oba forget it too.
Nothing on this page, and nothing Oba says, tells anybody whether an address has an Oba account.
No Oba account for that address yet? Oba is invitation only, and the founder reads every request himself.
