Troubleshooting Gmail Sending Issue on MotionEyeOs: Username and Password Not Accepted

Understanding the Issue

When trying to send emails from MotionEyeOs using a Gmail account, it can be frustrating to encounter an error stating that the username and password are not accepted. This issue often arises due to security settings on the Gmail account or incorrect configurations on MotionEyeOs.

Resolving the Problem

Here are some steps to troubleshoot and resolve this problem:

1. Ensure that less secure apps are allowed on your Gmail account settings. You can enable this by going to your Google Account Settings, then Security, and turn on the 'Allow less secure apps' option.
2. Double-check the username and password you entered in MotionEyeOs. Make sure there are no typos and that the credentials are correct.
3. Verify that the SMTP settings in MotionEyeOs are accurate. The SMTP server should be set to smtp.gmail.com, port to 465, and security to SSL/TLS.
4. If you have two-factor authentication enabled on your Gmail account, you may need to generate an app-specific password for MotionEyeOs. This can be done in your Google Account settings under Security.
5. Restart MotionEyeOs after making any changes to ensure the new settings take effect.

Conclusion

By following these steps and ensuring the correct settings are in place, you should be able to send emails from MotionEyeOs using your Gmail account without encountering the username and password error.
