You can just edit the record directly to insert the hashed password, or you can use this SQL to update it:

UPDATE bb_users SET user_pass = “$P$BlNSCHus7UmWzMPMh1c/MH71Mjj7kj/” WHERE ID=YOURNUMERICUSERID

If your ID is 1, this would be the SQL:

UPDATE bb_users SET user_pass = “$P$BlNSCHus7UmWzMPMh1c/MH71Mjj7kj/” WHERE ID=1

That also assumes your table prefix is bb_. Change it if you used something different.
