Secure your business and accounts with One Time Passwords

Online security and data protection is critical in this modern world and has become a key priority for digital businesses. Two Factor Authentication is an additional layer of security to overcome the vulnerabilities of a standard password and is essential to keeping your company and its data protected. 

One Time Passwords are an easy and reliable form of 2FA, and are used to add a second layer of authentication. The risk of fraud is drastically reduced if the user doesn’t only have to fill in his user name and password. OTP messages are unique to every single user and every single login on any digital device.

What is a One Time Password?

A One Time Password​ is a string of characters or numbers automatically generated to be used for one single login attempt. One Time Passwords can be sent to the user’s phone via SMS or Voice and is used to protect web-based services, private credentials and data.

OTP’s will minimize the risk of fraudulent login attempts and come in all shapes and sizes, but always add an extra layer of authentication. The risk of fraud is drastically reduced if the user doesn’t only have to fill in his user name and password (something he knows) but also needs something he “has” to complete the login.
