Signing in with a six-digit code

Updated 2026-08-21

Capital Prep is passwordless. There is no password to create, remember, or reset — you sign in with Google, or with a six-digit code we email you.

To sign in with a code

  1. Go to the login page and enter your email address.
  2. We email you a six-digit code. Leave the Capital Prep tab open.
  3. Type the code into the box on the "check your email" screen.

That's it — you're in, on that device, until you sign out.

Good to know

  • Each code works once and expires after 60 minutes. If yours has expired, just request a new one.
  • If you requested more than one code, use the one in the newest email.
  • Use the same email address every time. Your purchase, progress, and streak are all attached to the address you signed up with — a different address is a different (empty) account.
  • Signed up with Google? You can also use the email code, as long as it's the same address as your Google account.

Code not arriving? See "My sign-in code didn't arrive."
