Set Up Secure Folder auf Samsung
Secure Folder builds an encrypted container on your phone using Samsung Knox. Apps, photos, and documents placed inside stay separate from the rest of the system and open only after a separate password, PIN, pattern, or fingerprint check.
The feature ships pre-installed on Samsung phones with One UI, but it remains hidden until you set it up once. Open Settings ➔ Biometrics and security ➔ Secure Folder ➔ Agree, then follow the on-screen steps to sign in with your Samsung account and choose a lock type for the folder.
After setup, a Secure Folder icon appears on your home screen or in the app drawer. Apps you add inside run as separate installations with their own data, so they do not share history, files, or accounts with the regular version outside the folder.
If you only want to hide a handful of photos rather than build a full protected workspace, the lock option inside the Gallery app is faster and does not need a Samsung account. Secure Folder makes more sense when several apps or a mix of files need protection at once, since everything inside is encrypted as one unit and can be locked, hidden, or removed together.
