How to Put Password on OPPO F21s Pro 5G

The protection of personal data plays an important role in the usage of the smartphone. The device's memory stores not only personal photos and videos, but also passwords from social networks, as well as bank cards. Therefore, to protect sensitive information, you need to set a password on OPPO F21s Pro 5G.

The easiest and most reliable way to protect your privacy is to set a lock screen password. In this case, all the data of your OPPO F21s Pro 5G will be safe. The password will be required to access desktop and applications.

Open your phone settings.
Go to «Passwords & Security», then – «Password».
Select «Password».
Type in the password twice, then press «OK».

If you press the power button to lock the screen, Android will ask you to enter your password the next time you try to unlock the device. If you enter the characters successfully, you will have access to your device’s desktop.

Keep in mind that password is not the only way to protect your desktop. Depending on the firmware and features of the smartphone, other options may be available, such as PIN, graphic key, fingerprint, or facial unlock. The most reliable way to protect the device is to use a fingerprint, and the most convenient is facial unlock.

How to Put Password on Apps in OPPO F21s Pro 5G

Setting a password to unlock the screen already securely protects your smartphone. However, if your device is also used by another person, you can set your password to specific applications. It can be done in several ways.

Using Application Settings

Many applications, such as banking, offer to set a password the first time you start. Therefore, if you want to protect your funds, be sure to set it up after installing Sberbank, Tinkoff, Alfa-Bank or other applications of monetary organizations. There is a similar option in the settings of other applications that work with personal data.

Using Phone’s settings

If you need to protect an application that does not support setting a password through its own settings, you can use OPPO F21s Pro 5G system settings to protect it by following these simple steps:

Open your smartphone settings.
Go to Apps.
Select App lock.
Select applications that need to be protected.
Set the password to access selected applications.

Now, each time the selected applications are launched, the smartphone will require a password. Without it, you won't be able to access these apps.

Using special software

If OPPO F21s Pro 5G settings do not have the option of setting a password to applications, it is recommended to use special programs such as AppLock or CM Locker as an alternative method of protection.

Install a security application (for example, AppLock).
Set the graphic key or password.
Enter security email address.
Select the apps you want to protect.

The password to access the selected apps will be required as long as the AppLock app is installed on your smartphone. After it is uninstalled, the application lock is automatically removed.

How to Set a Password to OPPO F21s Pro 5G Gallery

Gallery is one of the most important applications for the owner of OPPO F21s Pro 5G, because through it you can access personal photos and videos. The Gallery application is protected in the same way as other programs. You can use system functionality or third-party applications such as AppLock to set the access password.
