Ohio State University Eliminates Password Expiration With New Passphrase Focused Policy

Similar to the recently discussed University of Pennsylvania policy change, Ohio State University (OSU) is also updating their password policy for students and faculty. They announced that they’re eliminating their current password expiration controls that required regular password changes every 180 days. The University shared that this change should save both their users and the IT department time and money previously spent helping people who forgot their new passwords following a mandatory change. They also hope this new policy will lead to fewer users recycling weaker passwords by making only small changes (like going from “Buckeyes1” to “Buckeyes2”) when regularly forced to choose new ones.

So how is the organization planning to preserve password security following this change? Similar to Univ of Pennsylvania, they are increasing their minimum password length to 15 characters with a maximum of 128. This is to encourage users to move away from shorter passwords to passphrases in hopes that these will be easier for users to remember while being harder for attackers to guess.

They are also pairing these passphrases with an existing multi-factor authentication (MFA) mobile app. While they don’t share details on whether MFA will be required during every login, they could only prompt for it when people log into their account from a new device or otherwise exhibit riskier behavior.

Finally, the university says that they will be monitoring passphrase use for signs they have been cracked or otherwise stolen. This seems to include watching for third-party breach data dumps that may include credentials used by school users. Then their security team can force a password change when it really matters instead of when the calendar says to.
