About Password Cache Regeneration
The password cache is stored using the most appropriate encryption method based on the information obtained during FIDO authentication.
Basically, a password cache is generated and used for each authentication information. However, the password cache may need to be regenerated due to differences or changes in authentication methods, such as the following

- Change of Windows password
- Differences in devices used for smartphone authentication
- Differences in authentication routes (direct logon, remote desktop logon)
- OS and software updates of PCs and smartphones

If you need to regenerate the password cache, you will be asked to enter your Windows password again at the time of logon, so please follow the instructions on the screen to enter the password.
