when the transition of the integration to OAuth is planned or how to make this transition

Good day, received a letter from GOOGLE gmail, please tell me - how to switch to integration with mail on OAuth? Please add OAuth protocol support. Below is the text of the letter: [Action required] Switch to applications that support the reliable OAuth protocol From September 30, 2024, access to Google Workspace accounts will be allowed only to applications with OAuth support. Password access will no longer be supported (except for the passwords of the applications themselves). POP and IMAP protocols will CONTINUE to work. They can still be enabled for applications that perform OAuth authentication. Dear administrator! As we have already reported in the blog, from June 15, 2024, we will disable access for less secure applications, that is, third-party applications that use only a user name and password (basic authentication) to log into a Google account. What you need to know When accessing using basic authentication, accounts are more vulnerable to hacking requests. In the future, access to the Google Workspace account will be possible only for applications that support the more modern and reliable OAuth protocol. Disabling access for less secure applications will take place in two stages: On June 15, 2024, the settings for less secure applications will be removed from the admin console, and you will no longer be able to change them. After this date, users who are allowed to control their access to less secure applications will still be able to connect to them. While users for whom applications of this type are disabled will no longer be able to use them. This also applies to those third-party applications in which access to Gmail, Google Calendar, and Contacts requires only a password and authentication is performed using protocols such as CalDAV, CardDAV, IMAP, SMTP, and POP. The settings that enable or disable IMAP will be removed from the user's Gmail settings. Users who gave less secure applications access to their accounts before the above date will be able to use them until September 30, 2024. From September 30, 2024, access to Google Workspace accounts will be disabled for all less secure applications. CalDAV, CardDAV, IMAP and POP will stop working if only password is used for login. Users will need to switch to a more reliable access method, which is called the OAuth protocol. What you need to do In order for users to still be able to sign in to such applications with a Google Workspace account, inform them that they must switch to a more reliable authentication method called the OAuth protocol. A list of users affected by the changes is attached to this letter. This authentication method allows applications to log into accounts using a digital key instead of a username and password. To make it easier for your organization's users to make the necessary changes, we recommend sending them the instructions in this PDF file. If your organization uses self-developed tools, you will need to add OAuth support to them. Instructions for developers are also included in this PDF file. Setting up the management of mobile devices If your organization interacts with a mobile device management provider to configure IMAP, CalDAV, CardDAV, or POP profiles, support for these services will be discontinued in accordance with the schedule below. Starting June 15, 2024, password-based synchronization with Mobile Device Management for IMAP, CalDAV, CardDAV, and POP will stop working for clients trying to connect for the first time. If you use Google Mobile Device Management, you will not be able to enable the "Selective synchronization" option for CalDAV and CardDAV. From September 30, 2024, password-based synchronization using mobile device management for IMAP, CalDAV, CardDAV, and POP will stop working for existing users. Administrators will need to sync their Google Accounts with a mobile device management provider to re-add those accounts to iOS devices that use the OAuth protocol. If you use Google Mobile Device Management, the options "Selective synchronization - CalDAV" and "Selective synchronization - CardDAV" will no longer work. Additional information about settings is provided in the article Applying settings on iOS devices. Other less secure applications For other less secure applications, ask the developer to add OAuth support. Scanners and other devices If scanners and other devices use the SMTP protocol or less secure applications to send e-mails, configure OAuth, an alternative authentication method, or set an application password for the device. In case of device replacement, we recommend choosing a model with OAuth protocol support. We are always ready to help If you have any questions or need help, contact Google Workspace support. During a conversation or when sending a request, tell the code 319688531. Thank you for choosing Google Workspace! Google Workspace team
