Forgot your Samsung PIN or password?

What still works, what wipes the phone, and when a lab can help.

If the screen lock was changed less than 72 hours ago, a supported Galaxy on One UI 6.1 or later may accept the previous PIN, pattern or password — if you know it and it was not deleted. A factory reset erases data held on the phone. Check for backups and talk to us first: some Galaxy models can be opened by our forensic tools without wiping them.

Which lock is it?

Three passwords that people mix up

A Galaxy may ask for a screen lock, a Samsung account login, or a Google Account after a reset. These protect different things, so the next step depends on which one is stopping you.

Screen lock

PIN, pattern or password

Controls access to the device and its encrypted data. A known previous lock may help on supported phones when the 72-hour option still applies.

Samsung account

Account email and password

Signs in to Samsung services. Recovering this account changes the account login; it does not remove a forgotten screen lock.

Google Account after a reset

Factory Reset Protection

A protected device may ask for a previously linked Google Account after a factory reset. Restoring account access does not restore local files erased by that reset.

This checker gives general guidance, not a model-compatibility or recovery guarantee. The laboratory must assess the exact model and its condition.

Still open somewhere?

If the phone is still unlocked, don’t restart it

Use the access you still have. Back up important data while the phone still opens. Avoid restarting it solely to solve a forgotten PIN; a flat battery can also lead to a restart.

Extend Unlock is conditional. It only helps if it was already configured and its trusted conditions are still met. After an initial unlock with the screen lock, it may keep the phone unlocked for up to four hours, but access can end earlier.

A restart does not erase your files. After restarting, the PIN, pattern or password is required before credential-encrypted storage can be accessed.

Access can change after a restart.

Already accessible

Back up accessible data

Use the access that remains.

Samsung’s previous-lock option

The previous screen lock: 72 hours, 3 tries

Changed the screen lock recently? On a supported Galaxy, the previous PIN, pattern or password may still let you set a new one without erasing the phone.

A maximum 72-hour previous-lock windowThe window starts when an eligible screen lock changes. It ends after 72 hours, or earlier if the previous lock was deleted. 72HOURS MAX
A short window, with conditions

The clock starts when the lock changes.

Samsung temporarily retains the previous lock for up to 72 hours. Deleting it early removes this option.

All four need to be true.

  • Supported softwareA Galaxy that supports the feature on One UI 6.1 or later.
  • A recent changeAn existing PIN, pattern or password changed within 72 hours.
  • The old lock is knownYou remember the previous PIN, pattern or password.
  • It was keptThe previous lock was not deleted when or after it changed.

If the option is already shown

The wording varies with the lock type and software version.

  1. Choose the previous-lock option

    Tap Forgot PIN?, Forgot password? or Forgot pattern? when it appears.

  2. Use the previous lock you know

    Enter that exact previous PIN, pattern or password carefully. Do not test guesses.

  3. Set and confirm a new screen lock

    Follow Samsung’s on-screen instructions, then back up the data you need.

Don’t create more failed attempts to reveal the link. Samsung says it appears after five or more failed unlock attempts; that is not a reason to keep guessing. If the option is missing, the time has passed or any requirement is uncertain, ask for a model check before a reset.

Google’s Find Hub

What Find Hub can and can’t do for a locked phone

Find Hub can help locate or secure a phone. It does not remove its existing screen lock or open the photos behind it.

Locate and secure a device, without unlocking itA conceptual street map with a location pin and a locked phone. This is an illustration, not a live map.
Location information is separate from access to the data. Illustration only.
  • Locate

    Shows an available device location. That may be current, a recent stored location or a supported offline-network result.

  • Play sound

    Can ring the device at full volume for five minutes, even if it is set to silent or vibrate.

  • Mark as lost

    Secures the device with its screen lock and can show contact information. It does not unlock the phone.

Remote actions have requirements.

To secure or erase remotely, the phone needs power, mobile data or Wi-Fi, its Google Account, Find Hub enabled and visibility on Google Play.

Offline finding is different.

Recent encrypted locations or the Find Hub network may help locate an offline device, depending on its settings and support. An available location does not unlock it.

What changed, and what wipes the phone

Remote unlock has gone. A reset still erases everything.

Getting a phone working again and keeping its existing files are different goals. Before choosing a method, establish what happens to the data.

TWO DIFFERENT OUTCOMES Remote unlockNo longer offered Factory resetLocal files erased A working phone does not mean recovered files.
Remote unlockNo longer offeredFactory resetLocal files erased
Conceptual illustration: restoring access to the handset can come at the cost of its stored files.
01

Remote unlock is no longer offered

Samsung no longer offers remote screen unlocking through SmartThings Find. Older guides may still describe it. Samsung’s standard route for a locked Galaxy is a factory reset when an applicable previous-lock option is unavailable.

02

A factory reset wipes the phone

A reset started from recovery mode or remotely erases the phone’s local photos, messages, apps and settings. On a protected phone, verification afterwards may ask for the previous screen lock or a previously synced Google Account.

03

Check what an unlock app actually does

Some “Samsung unlock” tools remove the screen lock by resetting the phone. The result depends on the exact method, model and software. If the method uses a reset, the existing local data is erased.

Find another copy first

Before any reset: five places to look

The phone may be locked while a separate copy of your photos or messages is still accessible elsewhere. Start with the accounts and devices you already used.

Cloud accountsMemory cardSent copies Locked phoneSEPARATE COPIES · ONLY IF PREVIOUSLY SAVED
Cloud accountsMemory cardSent copies
These are places to check for existing copies. They do not unlock the phone or create a backup of data that was never saved there.

Checking is different from restoring. Some services let you view files online. Other backups need a compatible device and an authorised restoration process to read their contents.

  1. Google Photos

    Sign in with the Google Account used on the phone and look for photos and videos already backed up.

    Open Google Photos
  2. Google Drive and account backups

    Check for saved Drive files, Google Account device backup records and Android WhatsApp backups.

    A backup record is not a browsable folder. Restoring some device data can require the previous screen lock. Restoring a Google Account WhatsApp backup needs the same phone number and Google Account. An encrypted backup also needs its configured passkey, password or key.

    Open Google Drive
  3. Samsung Cloud and OneDrive

    Samsung Cloud may hold contacts, settings and other supported backups. Its portal shows a summary; backup contents need a compatible device to restore.

    Gallery sync to OneDrive ended on 30 September 2026. Photos already saved in OneDrive remain there; check the OneDrive app for those copies.

    Check Samsung Cloud Open OneDrive
  4. The microSD card

    If the phone is already off and safe to handle, its removable card may hold readable photos. If the phone still opens, back up accessible files first; do not restart it just to check the card. Encrypted or damaged cards may need assessment.

    A remote erase may leave an SD card untouched. If the computer asks to format the card, cancel. Leave cards in hot or physically damaged devices for an engineer to assess.

  5. The people you sent photos to

    Recipients may still have copies in messages, emails or shared albums. Ask them to send the originals where possible; forwarded or compressed versions may have lower quality.

Found something important? Save a separate copy and confirm it opens before deciding what to do with the locked phone.

Questions people ask

More about a locked Samsung

The model, software and lock state determine the options. Start with the routes that preserve the data you want back.

Can you unlock a Samsung if you forgot the password?

Sometimes. If you recently changed a known screen lock, Samsung’s previous-lock feature may help on a supported phone. Check the previous-lock requirements first. Other data-preserving options depend on the exact model and software. Some Galaxy phones support forensic unlocking or extraction without a reset; a model check establishes whether that route is available.

How do I reset my Samsung if I forgot my password?

Samsung provides factory-reset routes through recovery mode and supported remote services. A factory reset erases the phone’s local data, so look for existing copies and check recovery options before proceeding. Depending on the reset route, device protection may require the previous screen credential or a Google Account previously synced to the phone.

Will my Samsung account password open the screen?

No. Your Samsung account password signs you in to Samsung’s online services; it is separate from the screen PIN, pattern or password. Changing the account password does not change the phone’s screen lock.

Can a Samsung service centre unlock it?

Ask the service centre exactly what it proposes and whether the process erases local data. A reset can make the phone usable again while removing the files you want to recover. If those files matter, establish whether a supported data-preserving route is available before authorising a reset.

Is there a way to bypass the PIN?

There is no universal, safe do-it-yourself PIN bypass. Check the proposed method carefully: a reset erases local data. On supported Galaxy models and software versions, our licensed forensic tools may unlock the phone or extract data without erasing it. We assess the exact phone and only work for its owner or someone with legal authority.

Why the data can’t simply be copied off

The screen lock is part of the key.

A modern Android phone’s private files are protected by encryption, with keys tied to its security hardware and credential protections. Connecting a locked Galaxy to a computer does not normally expose those files.

That is why the route depends on the model. On supported Galaxy models and software versions, our licensed forensic tools may unlock the phone or extract data without a reset. We check the exact model free and explain what is supported before recovery work.
