BibStack uses a one-time code sent to your email instead of a password.

Sign in with a code

BibStack doesn’t use passwords. Each time you sign in, we email you a 6-digit code.

  1. Open BibStack and enter your email address.
  2. Check your inbox for an email from BibStack with your code.
  3. Type the 6 digits into the app. It signs you in as soon as the last digit is entered.

If you’re new, the same steps create your account.

Set up your profile

The first time you sign in, BibStack asks a few quick questions. Each step saves as you go, so you can stop and pick up where you left off.

  1. Your name, and a profile photo if you like.
  2. Your racing profile: date of birth, gender and racing category. These are used for age grading, age-group places and Boston qualifying times.
  3. Preferences: units, race reminders and tips emails.
  4. Your first race, which you can skip and add later.

Your date of birth is never shown publicly.
