My mysql password = '' i try to login to PhpMyAdmin (on Ubuntu 10.04 lamp) and get error: Login without a password is forbidden by configuration (see AllowNoPassword) What should i do for enter to phpMyAdmin without set password? Thanks


You can turn on the option AllowNoPassword on file /etc/phpmyadmin/config.inc.php.

Edit the file config.inc.php, search and uncomment this line:

// $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

Then you can access PhpMyAdmin without password.

  • This command can help (tested on Ubuntu 10.04): sed '/^ .*AllowNoPassword.*/ s/\/\///' /etc/phpmyadmin/config.inc.php > /tmp/conf.tmp && mv /tmp/conf.tmp /etc/phpmyadmin/config.inc.php – Netum May 21 '10 at 13:51

    Thanks, I make that, after that i restart apache and mysql but i still get: Login without a password is forbidden by configuration (see AllowNoPassword) – Yosef May 21 '10 at 14:07
  • I also run: sudo sed '/^ .*AllowNoPassword.*/ s/\/\///' /etc/phpmyadmin/config.inc.php > /tmp/conf.tmp && mv /tmp/conf.tmp /etc/phpmyadmin/config.inc.php but i get: mv: try to overwrite /etc/phpmyadmin/config.inc.php', overriding mode 0644 (rw-r--r--)? y mv: cannot move /tmp/conf.tmp' to `/etc/phpmyadmin/config.inc.php': Permission denied – Yosef May 21 '10 at 14:10
  • Try to get root before run the command. Execute: sudo -s and then the sed command. Finally, ajust the permissions: chmod 640 /etc/phpmyadmin/config.inc.php && chown root:www-data /etc/phpmyadmin/config.inc.php – Netum May 21 '10 at 14:51

    I don't believe this solution works anymore in Ubuntu 14.04. I edited /etc/phpymyadmin/config.inc.php to uncomment/enable that line, run sudo /etc/init.d/apache2 restart, refresh the website, try and login with root and no password and the AllowNoPassword error continues to occur. – bafromca Jan 19 '15 at 22:47

Here is what I have noticed from attempting to solve this problem. what I went through:

  1. I set $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
  2. I go to phpmyadmin and login fine without password ..No problem

Then I wanted to run apache with a different user than www-data so I

  • I go to /etc/apache2/eenvvars and I edit export APACHE_RUN_USER=myuser and export APACHE_RUN_GROUP=myuser

I restart apache2 and when I try to login to phpmyadmin without password it does not let me event though, as I previously mentioned, I set $cfg['Servers'][$i]['AllowNoPassword'] = TRUE.

To resolve it

  • I go to /etc/phpmyadmin/
  • check the permission (run ls-l)
  • I notice that it is root:www-data for config-db.php and for config.inc.php
  • I run sudo chown root:myuser
  • Restart apache
  • Then go to phpmyadmin and login with passowrd...It works

If you run apache with a different other than www-data (i.e you own) and your config.inc.php and config-db.php are owned by www-data, then phpmyadmin will not

  • Thanks! The file now being chowed to the www-data user was the problem I had, great help! – Gary May 24 '19 at 6:58

use Sudo to access the following file that mention above (etc/phpmyadmin/config.inc.php.) and also stop apcaha before editing this file with this

// $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

else it will wont allow you to update it. Command for stopping apcahe

sudo /etc/init.d/apache2 stop

hope it will help it works for me


Open phpmyadmin config file

sudo nano /etc/phpmyadmin/config.inc.php

/* Uncomment the following to enable logging in to passwordless accounts,
     * after taking note of the associated security risks. */
     $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
