Authentication Change for EFS-Web and PAIR

EFS-Web and Private PAIR users will no longer be able to authenticate using PKI certificates as of February 15, 2019. There is now a new, safer, and simpler login method using a account. The USPTO is moving from using PKI certificates for two-factor authentication because the software will no longer be supported. Frequently asked questions and answers can be found in the FAQ section below.

How does logging in with help you?

  • Eliminates shared credentials: practitioners no longer need to share accounts with support staff because they will all have their own accounts.
  • Modernizes security processes with two-step authentication: username and password plus a one-time code delivered by email or mobile device application.
  • Saves time by granting access to multiple USPTO systems with one consolidated sign-in process.
  • Ensures USPTO compliance with the latest Federal Information Security Management Act requirements.
  • Helps resolve browser compatibility issues.
  • Gives users access to EFS-Web and Private PAIR until the planned full release of Patent Center in 2020.
