As of February 2025, Google has not announced plans to discontinue OTP (One-Time Password) logins for user accounts. However, significant changes are underway concerning authentication methods, particularly affecting third-party apps and devices.

Transition to OAuth for Third-Party Apps**

Google is enhancing account security by phasing out Less Secure Apps (LSAs) that rely solely on username and password authentication. This change primarily impacts third-party applications accessing Google services like Gmail, Calendar, and Contacts. Key dates include:

-March 14, 2025**: All users must use OAuth with third-party apps to access Gmail, Google Calendar, and Google Contacts. 

OAuth is a more secure authentication method that doesn't require sharing your password with third-party apps, thereby reducing potential security risks.

Impact on App Passwords**

While the discontinuation of LSAs affects password-only access, it's important to note that App Passwords—unique codes generated for specific applications—may still function. However, transitioning to OAuth is recommended for enhanced security and compliance with Google's updated policies.

Recommendations for Users**

- **Review Third-Party App Access**: Ensure that any third-party applications you use are updated to support OAuth authentication.

- **Enable Two-Factor Authentication (2FA)**: Strengthen your account security by enabling 2FA, which can include OTPs generated by authenticator apps.

- Consider Authenticator App Alternatives: While Google Authenticator remains a viable option, other apps like Authy offer additional features such as encrypted backups and multi-device support. 

By staying informed and updating your authentication methods, you can maintain secure access to your Google services amidst these changes.
