Sign in with a text message
Link your mobile once, then sign in with a 6-digit code instead of a password.
Phone sign-in is a third way into your account, alongside email and password and Google. It is worth setting up before you need it: it is the fastest way back in from the shop floor, and it does not depend on remembering anything.
Link your number
- Dashboard → Profile → Phone sign-in.
- Enter your mobile with the country code, like
+1 555 123 4567. - Send code, then type the 6 digits and Verify & link.
One number per account, and a number can only be linked to one account — if it is already on another login, linking is refused rather than moved.
Signing in with it
On the sign-in page choose the SMS option, enter the same number, and type the code.
Codes are 6 digits and last 10 minutes. Asking for a new one cancels the previous one, so if two texts arrive, the newer code is the live one.
When no text arrives
Check you linked that number. The sign-in screen looks exactly the same whether a number is on an account or not, and no text is sent for a number that was never linked. That is on purpose — otherwise anyone could type numbers into the form to find out who has a Booked account. If nothing arrives, the likeliest answer is that this number was never linked, or was linked to a different account.
Beyond that: 5 codes per number per hour, and 5 wrong guesses burn a code and require a new one.
It still works after STOP
If you have ever replied STOP to a shop's appointment texts, sign-in codes keep arriving. They are a message you asked for, at the moment you asked for it, and an unrelated opt-out should not lock you out of your own account.
Removing it
Profile → Phone sign-in → Remove. Do this when you change numbers, and link the new one — a linked number you no longer control is a way into your account.
Signing up is still email-only. Phone sign-in is a way back into an account that already exists, not a way to make one.
