How to Delete OTPs in Google Messages on Android?

If you’re using two-factor authentication (and you should be), you’re probably getting a lot of text messages containing one-time passwords (OTPs). It’s a bit annoying to have to delete them manually, so why not let Google’s Messages app do it for you?

SMS OTPs may not be the most secure, but it is a very common choice for 2FA. Since, by definition, an OTP can only be used once, there is little danger in keeping it. It also means that there is no reason to keep them. So it’s easy to keep your messaging app clean.

We’ll be using Google’s email app. It is already pre-installed on many Android devices, but you can download it from the Play Store if you don’t have it. When you open the app, you will be guided to set it as the default app.

Next, tap your profile icon in the top right.

Select “Message Settings” from the menu.

Select “Message Settings”.

Go to “Message Organization” in Settings.

Go to “Organizing Messages”.

Now all you have to do is activate the “Automatic deletion of OTPs after 24 hours” function.

Enable “Automatic deletion of OTPs after 24 hours”.

As explained in the settings screen, this option permanently deletes all current and future OTPs. This is perfect because OTPs are only valid for a very short time, usually around 10 minutes. A 24-hour period is more than enough time to use the OTP, although you may consider opting out of receiving them via SMS.
