Can't Sign In, or Confirmation Email Not Arriving

TroubleshootingAccountLast updated 2026-08-02

Confirmation or invite email not arriving

  1. Check your spam folder. The first email often lands there.
  2. Check the spelling of the email address you registered (mixing up .co.jp and .com is common).
  3. If you're using a mobile carrier email address, it may be blocked by a domain allow-list setting. Adjust it to allow the email, then resend.
  4. Wait a few minutes and try sending it again.

Forgot your password

Reset it from "Forgot your password?" on the sign-in screen. The reset email can fail to arrive for the same reasons as above.

Two-factor code won't go through

  • Set your device's clock to "Set automatically." Authenticator app codes are generated from the time, so any drift will always cause a failure.
  • Enter the code right after it refreshes, not right before it's about to change.
  • If you still can't get in, use a backup code (see Setting up two-factor authentication).

Seeing "Your account has been suspended"

If you requested an account suspension yourself, you'll see restore instructions when you sign in. If this doesn't match what you did, please contact support.

Still can't sign in?
