Configure your smartphone to automatically lock after a short period of inactivity

While there’s no one-size-fits-all for how long it should take for your phone to lock following inactivity, generally, the earlier, the better — though, not at the complete expense of convenience. Consider setting an automatic inactivity lock on your smartphone after approximately five minutes or fewer, depending on preference. This, in turn, will help improve the security of your device and protect your personal information from unauthorized access.
