How to disable two-step verification on Android: a complete guide with risks and alternatives

Two-step authentication (2FA) is one of the most effective ways to protect your account Google and data on your smartphone Android. However, there are situations when the user needs to disable it: when selling a device, changing a phone number, or switching to alternative security methods. It is important to understand that disabling 2FA reduces the level of security, but in some cases this is unavoidable.

The disabling process depends on how exactly two-step verification was configured: via SMS, an authenticator application (Google Authenticator, Authy), backup codes or hardware keys (Titan Security Key). In this article, we will analyze all the current methods, including the nuances for different versions Android (from Android 8 Oreo to Android 15), as well as the consequences of disabling.
