Signing in

This page signs in one copy of Oba, and it opens itself when you ask it to: type /login in the Oba window and your browser lands here with that copy's own short code.

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 no six digits arrive

Wait a minute and ask again. One address is sent one code a minute, so a second attempt inside that minute is not sent at all.

If the digits are refused

A code lasts an hour, and five wrong tries end that code. Ask for a new one and type the newest six digits you were sent.

If the right digits still do not sign you in

There is no Oba account for that address yet. Request an invitation.

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.
