If you've forgotten a password, try the self-service reset first. If that fails, submit a support request.
Use self-service reset
Most BTS-managed accounts support self-service password reset. Look for a 'Forgot my password' link on the sign-in page and follow the prompts using your registered recovery method.
If self-service isn't available
If you don't see a reset option or your account is locked, submit a support request with the category 'Password or account access'. Include the affected username and never send your current password.
Security note
BTS will never ask you to provide your password through an unsecured form, email, or chat. Always use approved channels.
