Keywords: , , , , , ,

The password of the university’s student and staff user accout as well as of a temporary UFO user account also must be changed at least once a year. You get the reminder to your e-mail if you have not changed your password during the year.

Change the password in the university’s service: https://account.oulu.fi/passwd.

Good password:

  • The length is 12 – 32 characters:

– at least one letter lowercase (abc…), but no Scandinavian characters (åäö)
– at least one letter UPPERCASE (ABC…), but no Scandinavian characters (ÅÄÖ)
– at least one number (123456…)
– the new password must differ on at least five characters from the previous one and furthermore, there must be at least one character in it which was not found in the previous password.

  • Do not use special characters because they cause problems in the external services (for example print service and O365)!
  • Avoid passwords based on repetition, dictionary words, letter or number sequences, usernames, or biographical information like names or dates.

  • Do not use the same password in other connections!
