My case is that i have HA between two FTD 4100 handle traffic and managed by FMCv

If the FTD's are setup in HA, you can failover traffic to one appliance whilst you reset the password on the other device. Traffic should not be interrupted as the FTD's are setup to be HA. To be on the safe side, do the work out of hours and double check the failover status before you do the work.

Here is the guide to reset the password on a FPR-4100 hardware device.
