Is there a way to reset an admin account's password by modifying the MySQL directly?

I've found the craft_users table where the hashed password is stored but I don't know how to hash a string so that it will be read correctly by Craft.

Craft uses Yii's CPasswordHelper::hashPassword which is a Blowfish hash algorithm, using PHP's crypt function with a "blowFishHashCost", which is a setting that can be found through craft()->config->get('blowfishHashCost')

You could use the SecurityService::hashPassword function to generate a new password, echo it, and update it in the DB manually: craft()->security->hashPassword('NewPassword');

  • Thanks! This is really helpful. Is there any way this can be done in a Twig template? Or can the hashPassword function only be called from a plugin? Feb 19 '16 at 12:57
  • i'd setup a temporary plugin (just the handle; ResetPlugin.php with an init function, in the init function you "Dump and Die" (Craft::dd(SecurityService::hashPassword('test'))) and after that, you delete it :)

    Just in case anyone else needs to do this, I made a plugin here: github.com/bravokiloecho/craft-password-helper Feb 19 '16 at 17:38

    This tweet shows you how to reset the password to secret -> twitter.com/nystudio107/status/1063135843441954816 Dec 19 '18 at 19:49

Future me, looks like you forgot your password again and locked yourself out of Craft. You also made your way back to this Stack Exchange question with @chris' perfect answer. Good! And to make your life really easy this time around, I've already generated a password/hash combos for you that works:

|--------------|---------------------------------------------------------------|
|  *Password*  |                        *Resulting Hash*                       |
|--------------|---------------------------------------------------------------|
|  password    | $2y$13$i1fEVeKiboWR/Hx07N9JtuSZj46KNueAg0IgpwL2TId0sXN.oyibC  |
|--------------|---------------------------------------------------------------|
|  NewPassword | $2y$13$YA.7RIgllODUDcmQPf/.FuXjOmKJYot5QxpFhhf4og9fdJWsIPWK6  |
|--------------|---------------------------------------------------------------|
|  admin       | $2y$13$Nlvh.kEu8FLIITusfjzQgOIIDryqLnJ3TsV/1UINRCFLfVnjJtILK  |
|--------------|---------------------------------------------------------------|

Update: The hashing algorithm didn’t change in Craft 3, so the above combo still works.

    Craft 3: Drop this in a template to render a new password hash {{ craft.app.security.hashPassword('NewPassword') }} Output: $2y$13$3hcn0v5fVCFB28GS3HNJfez3.MY/HaJnomkESPsy7cEN/Hx9skjLq Apr 23 '18 at 20:52

    I come back to this answer with embarrassing frequency. Aug 15 '18 at 18:43

    See these are the kind of people I love. I don't want to know how to generate the damn password, I just want to login into my local version so I can resume work. I will change it later once I log in. Thank you!

    Wish I could vote for this every time I come back and grab this hash. Would be properly embarrassing just how many votes I would have given it now.

If you don't want to mess about trying to insert code in the Craft/Yii stack, v3 just calls password_hash():

password_hash($your_password_string, PASSWORD_DEFAULT, ['cost' => 13]);

As a possibly helpful addendum (I was just trying to run the site locally and needed to log in); if you find you still can't login after changing the password via the database and are running PHP locally, it might be because you're accessing via socket and should add this to config/general.php:

'requireUserAgentAndIpForSession' => false,
