Previously in SugarCRM, the following statement was enough:
UPDATE users SET user_hash = MD5('PASSWORD') WHERE user_name = 'USERNAME';
I can't find a single site on how to do it now with SuiteCRM?
I found this:
Can I still use MD5 passwords? I’m used to that and can easily administer passwords in the database using just MD5.
Sugar will still recognize passwords stored in MD5 format, but anytime a password is changed it will convert to the newer format. Unless very old PHP build (5.2) used in a system where better crypt() is not available, new password will use salted hashing algorithm.
Posted it on SugarCRM's site:

It turns out that SuiteCRM uses this new password format too, but, as well, it still recognizes md5 passwords, so, same sql statement works:
UPDATE users SET user_hash = MD5('PASSWORD') WHERE user_name = 'USERNAME';
I did it and it works :)
Btw, same post recommends change passwords with PHP crypt like this:
crypt(md5("newpassword"))
Maybe it can help someone else.
