Method 1: Lock the Gallery app using Privacy and app encryption
This is the most popular method. It locks the entire Albums app, so anyone who opens your gallery must enter a password first. The exact menu names can vary slightly depending on your Funtouch OS version.
Open the Settings app on your vivo phone.
Tap Fingerprint, face and password (it may appear as Security or Fingerprints and passwords).
Select Privacy and app encryption.
Set a privacy password if you have not already, usually a numeric PIN or pattern.
Set up your security questions and save the answers, as you will need them to reset the password.
From the list of apps, find Albums (the Gallery app) and turn on the toggle next to it.

Once enabled, the Albums app will ask for your privacy password every time it is opened. You can also lock related apps such as File Manager from the same screen.
Method 2: Hide private photos and videos using File Safe
If you only want to hide a few specific photos rather than lock the whole gallery, File Safe is the better choice. It moves your selected files into an encrypted, password-protected vault, so they no longer appear in your regular gallery.
Open the File Manager app on your vivo phone.
Tap File Safe (it may also appear as Private Safe).
Set a password and security questions when prompted.
Inside File Safe, open the Pictures or Videos section
.
Tap Move in or Add and select the photos or videos you want to hide.
Confirm to move them into the encrypted vault.
Once moved, these files disappear from your normal gallery and can only be viewed after entering your File Safe password.
Method 3: Lock the gallery using i Manager (older Vivo phones)
If your vivo phone runs an older version of Funtouch OS (around 2.6 or below), the Privacy and app encryption option may not appear in Settings. In that case, you can use the i Manager app instead.
Open the i Manager app on your vivo phone.
Tap Privacy or App encryption.
Create a privacy password and set your security questions.
Select the Albums or Gallery app from the list to lock it.
Confirm your selection to apply the lock.
After this, the gallery on your vivo phone will ask for the password before showing any photos or videos.
Method 4: Add fingerprint or face unlock to your locked gallery
Entering a password every time can be slow. vivo lets you use your fingerprint to unlock encrypted apps, so you can open your gallery instantly while keeping it secure.
Open Settings and tap Fingerprint, face and password.
Select Fingerprint and add or confirm a fingerprint.
Turn on the option Fingerprint used for Privacy and app encryption.
Save the settings.
Now, when you open your locked gallery, you can simply use your fingerprint instead of typing the password.
