If you cannot avoid entering sensitive data on your computer, tablet or smartphone in public, we recommend that you implement the following security measures:
Tip 1 . Before entering the data, find the most suitable place : with your back against the wall, for example, you can get rid of unwanted glances.
Tip 2 . The use of privacy filters is also advised . Is about plastic sheets that, placed on the screen, make it appear black when viewed from an angle other than frontal. With them, reading the screen furtively becomes quite a bit more difficult.
Tip 3 . By applying two-factor authentication, the user must prove their identity through two independent components . Since access is then only granted if both data have been entered correctly and for a certain period of time, the level of protection is considerably increased . This method is often used, for example, in online banking, an area in which the identification usually consists of the combination of a password (first factor) and a TAN number (second factor), which is generated again with each access.
Tip 4 : Another way to protect yourself is to use a password manager. With this type of manager, you no longer have to enter the corresponding password every time you want to access an account, but the manager takes care of it and only asks for a master password as authentication . In this way, if someone were spying on what you type, they could not deduce the real passwords of the accounts, as long as you protect your master password with the necessary measures.
