There's nothing more frustrating than finding your phone won't let you in because you've suddenly forgotten your pattern or password . Whether you've dug out an old phone from a drawer or stumbled upon the code on your current device, that feeling of being locked out is maddening, but the first thing to do is stay calm so you don't permanently lock your device by trying too many passwords.

Fortunately, nowadays there are plenty of ways to solve this problem, as operating systems have evolved considerably. Depending on whether you have an Android or an iPhone , and the settings you've previously configured, you can regain access to your data without having to give up or necessarily resort to deleting everything, although that should be the last resort.

If you've been locked out, Google offers a powerful tool called Find My Device. For it to work, your phone needs to have internet access and location services enabled. Simply log in with your Gmail account, select your device, and choose the option to set a new password to regain access. If this doesn't work for you, the same tool allows you to perform a remote wipe, but be aware that this will erase absolutely all your data.

For Samsung users, things are even simpler thanks to SmartThings Find. This native app is fantastic because it allows you to remotely unlock your device by following instructions from your Samsung account, and it even works in situations where there isn't a stable internet connection, allowing you to manage backups before taking any drastic action through the customization of Samsung One UI.

On older Android models, there was a very useful feature linked to Gmail. After entering the wrong password about five times, the system would ask if you had forgotten it, allowing you to verify your identity with your email address to remove the lock. If none of this works, the only option is a factory reset. To do this, you must enter the recovery menu by pressing and holding the power and volume down buttons until you see the system menu and select "Wipe data/factory reset ," assuming your phone will be restored to its original state.

Automation and tricks to avoid typing the password

If you want to avoid the hassle of entering your PIN every few minutes, Android has a feature called Smart Lock. This tool allows your phone to stay unlocked if it detects you're in a trusted location , such as your own home, or if you're wearing a paired smartwatch. Simply look for "Trusted Places" in your security settings and mark the area on the map where you want your device to always be ready to use.

For iPhone users, iOS doesn't allow you to mark safe places, but you can use your Apple Watch as a key. If facial recognition or fingerprint scanning fails, the watch will automatically unlock your iPhone if you're nearby. However, this carries a security risk, as anyone wearing your watch could potentially access your phone. Therefore, it's crucial to understand the real risks and how to protect your iPhone.

There are also some very interesting third-party apps for managing the screen. For example, Easy Unlock or GravityScreen allow the phone to turn on or off using proximity sensors and accelerometers . You can configure the screen to activate when you shake the phone, turn it over, or simply wave your hand over the sensor, which greatly helps protect the physical power button from wear and tear over time, preventing problems similar to those that occur when an in-screen fingerprint sensor malfunctions.

It's not all about the home screen. Sometimes the problem is the SIM card. If you've exceeded your PIN entry limits, you'll need the PUK code to unlock your mobile line and restore call and data service.

It also happens that we block people on social media, and then, by blocking so many people, the contact we want to reconnect with gets buried at the bottom of the list . In these cases, if the user no longer appears on the usual blocked list but still can't message us, there's probably a synchronization error or the block has gotten stuck in some system loophole, forcing us to find alternative ways to contact them.

Today we have a huge variety of tools at our disposal, from factory resets and the use of Google or Samsung accounts to recover passwords, to smart features like Smart Lock or sensor-based apps that make our daily lives easier by avoiding the constant use of physical buttons and passwords in secure environments.
