How email-code sign-in works

We email a 6-digit code to sign you in; there is no password to remember.

• A code works once and expires after 10 minutes.
• Only the newest code works; requesting a new one cancels the old one.
• You can request another code after 60 seconds. Too many wrong attempts lock that code, so request a new one.
• Codes go to the address you entered. Check spam, and make sure you typed it correctly.
• Use Log out (or log out everywhere in Account settings) to end sessions.
