FAQ
No verification code?
Check spam first; one code per 60 seconds and max 5 per hour; corporate mail may take 1–2 minutes.
Why is a captcha required?
After one failed password attempt, the next sign-in requires a captcha to prevent brute force.
Account locked?
Five consecutive wrong passwords lock the account for 15 minutes; wait or use an email code.
Passkey not working?
Passkeys need HTTPS, a stable domain and a device with fingerprint/face/PIN; otherwise use a password.
Email not registered?
The email has no account yet; please sign up, or contact your administrator for provisioned accounts.
Password requirements?
8–128 characters with both letters and digits; the new password must be entered twice.
