Password......

Hello, can someone help me? I wasn’t able to take care of my NAS for a long time.
I can no longer log in—after “admin” it doesn’t accept my password anymore. This must have happened after a firmware update. I don’t want to lose my stored data.
What are my options?
I’m asking for help.

3-second reset — your data will remain intact.

Please make backups! (A RAID is not a backup, as you can see here)
