Since March 2022, Google has strengthened the security of access to your account via a third-party application.

For this, you should not use your own password to log into your account, but rather generate a password via your account.

To do that, make sure that your two-step verification is on. Now, go to the "Manage your Google Account", then click the "Security" tab.

Now, click the App passwords option. Finally, you can select a Custom name for your app.

Once the password is generated, you will have to put it in place of your real password.
