When you log in to an ESET HOME account during installation or after you have purchased the Premium version of ESET Mobile Security for Android, you may need to manually type your License Key to activate the premium product and access your premium features.
You will need your License Key from your ESET HOME account or from the email you received from ESET after your purchase.
Tap the menu icon in the top left corner of the screen to bring up the context menu and tap License.
Tap Enter a License Key.
Type your License Key (hyphens are added automatically) and tap Activate.
Tap Finish. Your license is activated and premium features are now available.
You can use your enabled Anti-Theft account and a Trusted friend's phone to help you reset your Security password and restore access to your device if you forget or lose your Security password.
