Your HAW account and password

More and more of HAW Hamburg's online services are using the HAW account number (e.g. aba123) for user registration. This account information is given to students with their enrolment certificate and to employees when they start work.

How do I change my password?

I've forgotten my password. What do I do?

My password only works with the HAW mailer system. What's wrong?

Resetting your HAW account with an mTAN

You're a student and you've saved your mobile number on myHAW?

Or you're an employee or external user and you've saved your mobile number on the self-service portal?

Then it's possible for you to reset your password with the help of a mobile TAN.

Important points about the mobile TAN (mTAN):

  • You can request an mTAN four times per day (at intervals of at least 15 minutes).
  • Every mTAN is valid for 15 minutes.
  • mTANs will only be sent to valid German mobile numbers.
  • Calls and text messages to the mTAN sender will be ignored.
