How do I turn off the mysql password validation

Question

It seems that I may have inadvertently loaded the password validation plugin in MySQL 5 7  This plugin seems to force all passwords to comply to certain rules   I would like to turn this off   I ve tried changing the validate password length variable as suggested here to no avail   mysql gt  SET GLOBAL validate password length 4  Query OK  0 rows affected  0 00 sec   mysql gt  SET PASSWORD FOR  app    PASSWORD  abcd    ERROR 1819  HY000   Your password does not satisfy the current policy requirements   I would like to either unload the plugin or neuter it somehow

If you want to make exceptions  you can apply the following  hack   It requires a user with DELETE and INSERT privilege for mysql plugin system table   uninstall plugin validate password  SET PASSWORD FOR  app    PASSWORD  abcd    INSTALL PLUGIN validate password SONAME  validate password so     Bland security disclaimer  Consider  why you are making your password shorter or easier and perhaps consider replacing it with one that is more complex  However  I understand the  it s 3AM and just needs to work  moments  just make sure you don t build a system of hacks  lest you yourself be hacked

Building on the answer from Sharfi  edit the  etc my cnf file and add just this one line   validate password policy LOW   That should sufficiently neuter the validation as requested by the OP   You will probably want to restart mysqld after this change   Depending on your OS  it would look something like   sudo service mysqld restart   validate password policy takes either values 0  1  or 2 or words LOW  MEDIUM  and STRONG which correspond to those numbers   The default is MEDIUM  1  which requires passwords contain at least one upper case letter  one lower case letter  one digit  and one special character  and that the total password length is at least 8 characters   Changing to LOW as I suggest here then only will check for length  which if it hasn t been changed through other parameters will check for a length of 8   If you wanted to shorten that length limit too  you could also add validate password length in to the my cnf file     For more info about the levels and details  see the mysql doc       For MySQL 8  the property has changed from  validate password policy  to  validate password policy    See the updated mysql doc for the latest info

Further to the answer from ktbos   I modified the mysqld cnf file and mysql failed to start  It turned out that I was modifying the wrong file   So be sure the file you modify contains segment tags like  mysqld safe  and  mysqld    Under the latter I did as suggested and added the line   validate password policy LOW   This worked perfectly to resolve my issue of not requiring special characters within the password

Here is what I do to remove the validate password plugin    Login to the mysql server as root mysql -h localhost -u root -p Run the following sql command  uninstall plugin validate password  If last line doesn t work  new mysql release   you should execute UNINSTALL COMPONENT  file   component validate password        I would not recommend this solution for a production system  I used   this solution on a local mysql instance for development purposes only
