DSM’s warning is a false positive.
If DSM strict requirements are scanned for:
- DSM requires Upper & lower case passwords (but how would it know the decrypted ?)
- DSM requires punctuation. Again, how would it know?
I say this because I use uuidgen to create a 256 bit random password for user plex, which cannot be logged into, for added security. Predicting the output of uuidgen is virtually impossible which makes the password virtually impossible to predict.
Anyone who does manually set the password for user plex is compromising their security and at their own risk.
