The old methods of connecting to mail no longer work.

Google has discontinued support for third-party apps that use only passwords to connect to Google Workspace services via CalDAV, CardDAV, IMAP and POP, as well as Google Sync. As a result, these apps will no longer be able to connect to Google Accounts. This was announced by the company on the Workspace Updates blog.

The company noted that the use of a password for authorization through third-party applications increased the risk of compromise of credentials and unauthorized access to accounts. In order to improve security, it was decided to discontinue support for this authentication method. Users who continue to use the old method of connection must switch to a more secure method, otherwise they will face the inability to log in through such applications.

Google recommends using "Sign in with Google", which is based on the OAuth security standard, which restricts access to third-party apps to specific permissions without sharing user credentials.

What to do if you are affected by the changes
If you're using an older client, such as Outlook prior to version 2016, Google recommends upgrading to Microsoft 365 or downloading the latest versions of Outlook for Windows or Mac. To do this, you will first need to back up your email in .pst format and then import it into the new version of the client.

Users who connect Google accounts through iOS or macOS apps must delete and re-add the account. This automatically activates OAuth. Instructions on how to connect an account on Mac are available on the Apple website.

For other email clients, such as Thunderbird, you'll also need to reconnect your Google account and set up IMAP with OAuth. Detailed instructions on how to set it up can be found on the support pages of the respective applications, such as Mozilla Thunderbird.

If you do nothing, you will receive an error message when you try to log in to your account and access will be blocked. The changes come into force on September 30, 2024.

For companies that are still using older protocols, the migration process will be more difficult, as it requires updating the entire network. Google provides detailed instructions for administrators on its support site.
