# Google G-Suite Two Factor Authentication

 * Does Postman SMTP support two factor authentication? The Postman plugin was working
   great until we enable two factor authentication this morning.
 * I checked the email logs and we were receiving the following errors:
    Token has
   been expired or revoked.(invalid_grant) Bad Request(invalid_grant)
 * I disabled the two factor authentication and tried to send a test email through
   the Postman plugin. I received the following error:
    Bad Request(invalid_grant)
 * I wasn’t sure what to do at this point but I noticed the following in the Postman
   configuration menu: Grant permission with Google. I went through the steps and
   tried a test email. Everything seems to be working again.
 * My question is, was this the correct way to address this issue? I am not sure
   if this screwed up the Postman settings or anything like that.
    It still shows
   the following so I believe we’re alright: “Postman will send mail via 🔐SMTP-
   STARTTLS to smtp.gmail.com:587 using OAuth 2.0 authentication.”
 * **Also, if we re-enable the two factor authentication will it work if we click
   on “Grant permission with Google” and follow the steps?**
 * Thanks for your help
    -John

 * We found a fix. If you enable two factor authentication for Google G-Suite all
   you have to do is click on “Grant permission with Google” under the Actions Column
   in the Postman SMTP Settings. This will fix any issues and allow you to send 
   a successful test email.
