Accordingly, from now on, millions of Google users will not be able to access Gmail data from applications and devices that do not meet modern security standards. This means that only usernames and passwords will be used to log in.
This is considered part of a major campaign that Google launched a year ago, to improve security for all of its services. In recent times, the technology giant has been actively deploying new security technologies, including applying Chrome browsers to access locks on popular operating systems such as Windows, macOS, Linux and Android.
It is known that the new security system will switch to using the OAuth authorization protocol to help protect user data more effectively and better. Thus, users will not be able to access Gmail through protocols such as CalDAV, CardDAV, IMAP, POP and Google Sync with just a username and password.
However, these changes mainly affect Google Workspace users. Personal Gmail account owners do not need to worry about access to their mailboxes, but IMAP access via email applications will only be done through the OAuth protocol. This is a protocol that allows third-party applications to have limited access to data without requiring the user's login information and password.
At the same time, Google recommends that users take some necessary steps to avoid problems when accessing Gmail after the new rules take effect.
In addition, users of the Mail app on iOS and macOS will need to use the Google account login option to activate OAuth, which will require them to delete and add their accounts.
