DEVICES

Arcana, the game's own client, can stay signed in on a device: after you enter your password once, the game gives that device a sign-in key, and it comes back without asking for the password. The game keeps only a scrambled copy of each key, never your password, and a key that goes unused for 30 days stops working by itself. At most ten devices stay signed in as one character.

devices lists the devices that stay signed in as you, and when each was last used. forget number signs one of them out, and logout everywhere signs out all of them. Changing your password with passwd signs out every device too.
