How to Generate APP Password for Gmail Account usage in Yeastar

Follow

As the security of Google's email account is gradually improved, some clients may not be able to directly create a Google account even if you have checked a lot of possible failure reasons. In fact, many applications have enabled 2-step verification function to enhance security performance, such as having to enter the code in SMS or verification code in email again then you will be able to log into its server, but for mail clients such as pbx or outlook that cannot use 2-step verification function, you might have to try Google's APP password in system email setup.

    Please note if you change password for gmail account, app password will be removed and system email test will be failed, so the solution is go to step 12 and regenerate app password and replace the password in system email setup in PBX.

    If you can't find two-factor authentication on the 'Security' tab, you can search through the search bar on the Google account settings page itself.
