Grid Authentication

One-time password (OTP) without hardware tokens or software applications

Gemalto’s GrIDsure flexible authentication method GrIDsure Logo allows an end-user to generate a one-time password without the requirement for hardware tokens or software applications. GrIDsure tokens work by presenting the end-user with a matrix of cells which contain random characters, from which they select a 'personal identification pattern' (PIP).

Whenever a user wishes to authenticate to a protected resource, they are presented with a challenge grid containing random characters. The user then enters the characters in the cells that correspond to their PIP.

The end result is far superior to static passwords. Every time the challenge grid appears, the characters in the cells are different, so the user is always entering a one-time passcode. Plus, there's no hardware to lose.

GrIDsure is supported by SafeNet Authentication Service, and can be used to protect a wide range of use cases, including:

  • VPNs
  • Network logon
  • Cloud applications (Saas)
  • Web portals
  • VDI

Gemalto SafeWord was good enough for our needs, but we evaluated SafeNet Authentication Service and found it met all our requirements and was less expensive! We were already a happy customer, and we’re even happier now.
