when you create a password with dovecotpw or doveadm you can
copy&paste the generated password into your database.
If you use the same password scheme for all users you can use
"default_pass_scheme = ..." or as far as I know you can also override
the password scheme for the users in MySQL. Just insert the password
with the scheme prefix like "{SHA256}Password" into your MySQL
password field to override the default password scheme.
The query looks like
password_query = SELECT username, password \
FROM users WHERE username = '%u'
even for other password schemes than PLAIN...
