When you create an account we email you a six-digit code. Type it into the boxes on the sign-up screen to confirm your email address.
If the code doesn't arrive: check your junk or spam folder first, and make sure you're looking at the address you actually signed up with. The email arrives within a minute or two; if it's been longer than five, request a new one.
If the code is rejected, make sure you're using the newest one. Requesting a new code cancels the previous one, so an older email in your inbox will no longer work.
Forgotten your password? Use Reset password on the sign-in screen. The link is emailed to you and is single-use.
Still stuck, especially if you're locked out entirely, contact us. Being unable to sign in is something we treat as a real problem, not a nuisance.
