How to sign in

There are no passwords. Enter your phone number, and you'll get a six-digit code by text message. Enter the code and you're in.

The code expires after ten minutes. If it doesn't arrive, check that the number you typed is right, wait a few moments, and request another. Texts can take a minute during busy periods.

If you have accounts with more than one program, the same phone number gets you into all of them, and you can switch between them once you're signed in.
