Authentication by SMS

SMS authentication and 2FA is increasingly used to give employees access to the company network. Finding a strong password is becoming increasingly difficult and hackers are getting smarter. The use of inappropriate passwords can lead to a global loss, especially in the financial world

SMS authentication offers the right solution for this, because companies can send an automated SMS message over a secure connection to an employee's cell phone. The SMS message includes a unique code that provides access to the company's secure environment, confirming whether the user is actually who he or she claims to be. This significantly improves the security of company networks and online workstations and SMS authentication provides cost savings as physical tokens can be replaced by a 2FA code per SMS.
