We may have the situation that after changing a new password, we forget the new one in the next day. Then we tried serval times with some combinations. That may cause the ID locked by the system due to input wrong password serval times. The only way to solve the problem is to notify the administrator and reset the password.

The invention disclosure introduces a double password mechanism to avoid the problem. Both of the old and new passwords are valid to the system in a overlap duration. They could be backup for each other. And also there should be a synchronize process for the two password field periodically.

This invention disclosure resolves following problems.

1) Provide the user a new recovery mechanism to re-change their password.
2) Provide a redundant idea for all of similar system.

In the old authentication system, there are 4 columns in the DB. "Period" means user has to change password in 120 days. "Duration" records the passed days.

User ID Password Period (Day) Duration (Day)


We involve another 3 columns to store the new password in the new authentication system.

1) At the begining the new password is the same with the old password.
