In an ongoing effort to enhance user security, Google has announced the phasing out of SMS codes for user authentication in Gmail. These codes, once a staple for two-factor authentication (2FA), will be replaced by modern methods such as QR codes, passkeys, and dedicated authenticator apps. If you’re still dependent on one-time SMS codes, you could encounter serious access issues with your Gmail account in the near future. Don’t wait for the change—transition now to a more secure authentication method!
Why Google is Eliminating SMS-Based 2FA for Gmail
Since 2021, Gmail has utilized SMS codes as part of its two-factor authentication system (2SV).While they’ve been a reliable option for many users—especially those who don’t always have internet access—Google has deemed them outdated and vulnerable. Starting April 2025, any user without an alternative 2FA method will receive an SMS verification code by default.
A spokesperson for Google, Ross Richendrfer, confirmed that SMS-based verification is being replaced due to the increasing prevalence of phishing attacks specifically targeting SMS codes. Cybercriminals have devised tactics such as SIM swapping and misleading emails to steal these codes, exacerbated by AI technologies that can intercept them in real time.
As early as this upcoming year, users relying on SMS codes may find themselves unable to access their Gmail accounts. The transition is essential for enhancing account security.
How to Check If You’re Using SMS-Based 2FA
It’s crucial to determine whether SMS codes are your current 2FA method. Follow these steps based on your device:
- For web browsers: Sign in to your Google account and visit the My Account page.
- For Android users: Open the Google Play app, select your user icon, and then tap on Google Account.
- iOS users will need to launch the Google app from the App Store, tap their profile icon, and touch Manage your Google Account.
The following methods will be displayed under Second Steps:
- Authenticator or Passkey as Default: If you see green checkmarks next to Passkeys and Authenticator, you are already set up with more secure authentication methods. SMS codes will no longer impact your access.
- SMS 2FA as Default: If you do not have green checkmarks next to Authenticator or Passkeys, SMS codes are still your primary method. Double-check that your phone number also has a green checkmark.
Exploring Alternatives to SMS 2FA in Gmail
Now is the time to upgrade from SMS-based 2FA. Consider these modern alternatives:
1. Google Authenticator
For first-time users, it’s advisable to set up Google Authenticator via a desktop browser. Navigate to How you sign in to Google and select Authenticator, then click Get Started or Add/Change authenticator app.
On your mobile device, download the Google Authenticator app from Google Play or App Store. Your Google Authenticator will generate a QR code for you to scan using your phone, enabling time-based OTPs that refresh every 30 seconds.
2. Passkeys
Passkeys offer a convenient and secure way to sign in to your Google account across different devices using biometric methods such as fingerprint, facial recognition, or physical security keys.
To set up a passkey, head over to the Security page of your Google account. Under How you sign in to Google, select Passkeys and click Create a passkey.
You will be prompted to finalize the passkey setup using your chosen biometric or PIN method. Completing this process secures your account with alternative authentication.
Opting for either Google Authenticator or passkeys will put you ahead in the security game, shielding your account from vulnerabilities associated with SMS codes. Remember, avoid removing your primary phone number from your Google account to prevent potential login issues.
