Troubleshoot Issues With Google 2SV and Third-Party Apps

Issue

Users who use non-Google apps to access their UAH email, calendar, or contacts may receive an error stating that their username or password is incorrect despite being able to log in normally to Google apps or on their web browser.

Resolution

Apple Mail, Calendar, and Contacts

If your UAH Google account is linked to the Mail or Calendar app on iOS/MacOS, if you are syncing your UAH contacts to iOS/MacOS, or if you are using Outlook for Mac, try removing and re-adding your account. When you add it back, select sign in with Google to automatically use OAuth. This will prompt you to log in to your UAH Google account directly.

Microsoft Outlook

OIT recommends utilizing Google Workspace Sync for Microsoft Outlook (GWSMO). Learn how to set up GWSMO. Additionally, learn about the advantages of GWSMO over IMAP.

Alternatively, if you are using stand-alone Outlook 2016 or earlier, move to Office 365 (a web-based version of Outlook) or Outlook 2019, both of which support OAuth access.

Mozilla Thunderbird

If you are using Thunderbird, re-add your Google Account and configure it to use IMAP with OAuth2. Learn how to use OAuth2 with Thunderbird and Gmail.

Other apps

If you are using another email client, re-add your Google Account and configure it to use IMAP with OAuth2. If you use CalDAV to give an app or device access to your calendar, or if your Google Workspace account is syncing contacts to any other platform or app via CardDAV, switch to a method that supports OAuth.

Many applications now have a Sign in with Google option. This is the preferred method for keeping your account secure while using third-party apps. 

If your app doesn’t offer Sign in with Google and you cannot switch to a more secure app or device, you might choose to use Google's app passwords feature. An app password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account. Learn more about app passwords.

Environment

Non-Google applications including, but not limited to, Apple Mail, Apple Contacts, Apple Calendar, Microsoft Outlook, and Thunderbird

Cause

As of early 2021, Google Workspace accounts only allow access to apps using a secure access method called OAuth. When you try to access your Google account from a less secure app that doesn't use OAuth, you will be given an incorrect username/password error.
