If you’ve forgotten the password on your Samsung Galaxy Tab A, the only guaranteed way to unlock it is a factory reset, which erases everything on the tablet. There are exactly two exceptions, remote unlock services you must have set up before the lock, so check those first, but if they weren’t enabled, prepare to wipe the device.
The hard truth about your locked Samsung Galaxy Tab A
Being locked out of your own tablet is frustrating, but the reality is straightforward: there is no secret backdoor. For any Samsung Galaxy Tab A, a forgotten password means the device’s security is doing its job, and the only method that always works is a factory reset, which permanently deletes all local data, apps, photos, downloads, and settings. If you have a backup, this is a minor inconvenience; if you don’t, the data is gone. The two remote unlock options below can save your data, but they only work if you enabled them before the lock screen activated. If you didn’t, skip straight to the factory reset section, it’s your only path back in.
Before you wipe everything: Try these 2 remote unlocks
These two methods are the only ways to regain access without losing data, but both have strict prerequisites. If either service was active on your tablet before it got locked, you can unlock it remotely from another device. If not, they will fail, and you’ll need to reset.
Unlock with Samsung SmartThings Find
Samsung’s SmartThings Find (formerly Find My Mobile) can remotely unlock your tablet, but only if the “Remote unlock” feature was enabled on the device before it was locked. To use it, go to the SmartThings Find website on any computer or phone, log in with the Samsung account that was signed into your tablet, select your locked Tab A from the device list, and click the Unlock icon. You’ll verify with your Samsung account password, and the tablet will unlock remotely. This requires the tablet to be powered on and connected to the internet.
Unlock with Google Find My Device
Google’s Find My Device works similarly, but it doesn’t unlock the screen directly, it lets you set a new lock screen password. The tablet must be powered on, connected to the internet, signed into the associated Google account, and have Find My Device (sometimes called Find Hub) enabled beforehand. Visit the Find My Device website, log in with the Google account on the tablet, select your device, and choose the “Lock” option. You’ll enter a temporary password, which you can then use to unlock the tablet and change the screen lock. If the tablet is offline or the service wasn’t enabled, this method won’t work.
The 72-hour grace period for a new screen lock
On newer Samsung tablets running One UI 6.1 or later, there’s a brief window that can save your data. If you changed your screen lock within the last 72 hours and then forgot the new password, the lock screen will show a “Forgot” option. Tapping it may reveal a “Reset with previous screen lock” choice, which lets you enter the old password, the one you used before the recent change, to unlock the tablet without a factory reset. This only applies if the lock was changed recently, not if the original password was forgotten after long use. If you see this option, use it immediately; if not, it isn’t available for your situation. If you’re locked out of a phone instead, you can try the steps for when you forgot redmi password? here's how to unlock. If you're dealing with a different Android tablet entirely, the unlock onn tablet forgot password process offers a comparable recovery path.
How to factory reset your Samsung Galaxy Tab A (the guaranteed fix)
When remote unlock options aren’t available, a factory reset via Recovery Mode is the definitive solution. This works on every Samsung Galaxy Tab A model and bypasses the forgotten password by erasing the entire device. The steps below are performed using the physical buttons on the tablet, so no computer or account is needed.
- Turn off the tablet completely by pressing and holding the Power button, then selecting “Power off” from the screen.
- Press and hold the Volume Up button and the Power button simultaneously. Keep holding both until the Samsung logo appears on the screen.
- Release both buttons as soon as the logo shows, and wait for the Android Recovery screen to load. This may take a few seconds.
- Use the Volume Up and Volume Down buttons to navigate through the menu. Highlight “Wipe data/factory reset.”
- Press the Power button to select it. On the confirmation screen, navigate to “Yes” or “Factory data reset” and press the Power button again.
- Wait for the reset process to complete. This erases all data and settings on the tablet.
- When the reset finishes, use the Volume buttons to highlight “Reboot system now” and press the Power button.
The tablet will restart, and the first boot will take longer than usual because it’s rebuilding the system from scratch. When it finishes, the lock screen will be gone, and you’ll be able to set up the tablet as new. All personal data is gone, so if you have a cloud backup, restore it after setup.
The post-reset hurdle: Factory Reset Protection (FRP)
After the factory reset, the tablet will not let you straight in. Samsung and Google include Factory Reset Protection (FRP) as an anti-theft measure, so the device will demand the Google account credentials that were previously synced to it before the reset. If you remember that email address and password, you’re done, enter them and continue setup. If you don’t remember the Google account details, the tablet will remain locked at the setup screen, and you’ll need to follow a dedicated FRP bypass procedure for your specific Tab A model. This is a separate challenge from unlocking a locked tablet, and it requires its own steps, which vary by firmware version. The key point: before you reset, write down the Google account that was on the tablet, because without it, the reset solves one lock only to create another.
