where is password charecter lenght in android 11

hi 

ineed to know about password charecter lenght of android 10 or 11 in samsung models like a30 or a20 or a50

i know there is some field in xml file of huawei psmart "u0_lockscreen,hw_credential_len">24</string 

this is hint to what is number of password charecter

i want to know about samsung bfu backup and how can i find this field 

becuse there more phone with password alphanumeric if i know about lenght of password i can make my own dictionary for bruteforce

i find locksettings.password_quality in locksettings.db to know about type of password and that can be simple or adcance with symbol but dont know about lenght 

is there anyone to help me ?
