[E-trademarks] New authentication methods

Mon Oct 13 21:20:24 UTC 2025

I've been using Google authenticator for years because the PTO was at one point not very good about sending out the verification emails.  Never had any issues with it.

Subject: [E-trademarks] New authentication methods

Has anyone researched or have any thoughts on the new 2 step authentication methods required by the USPTO.  For example, has anyone used OKTA, Google Authenticator, or Microsoft Authenticator?

I am looking for the simplest to install/ use/ and configure across both Apple and PC devices.

Thank you!
