somewhere you must be setting the password something like this in local.conf
EXTRA_USERS_PARAMS += "\
useradd admin; \
usermod -p 'XXXXXX' admin; \
"
Now how you generate the password could be done separately via
something like ( for setting password to me 'test' )
python3 -c 'import crypt; print(crypt.crypt("test",
crypt.mksalt(crypt.METHOD_SHA256)))'
Replace XXXXXX with the output of the above cmd
aside from this its perhaps better to use sha512 than sha256
