What does "significantly differ from the old password" mean?
In the SafeGuard Easy manual, you can find the hint that a new password will be rejected if it is "significantly similar" to the old password or username.
"Significantly" is defined as a difference of at least 20%.
The following example shows how this is calculated:
The old password is 770505Xz. If this is changed to 770808Xz. The new password is rejected by SafeGuard Easy.
SafeGuard Easy does not count the digits that have to be changed but the digits that are allowed to stay the same. In this example, 6.4 digits may remain unchanged.
SGE discards the positions after the decimal point. This means that 6 digits may remain unchanged.
At this step, SafeGuard Easy has a slight imprecision:
For the example mentioned above, the system rejects a new password if >= 6 digits remain the same (instead of > 6 digits).
