Issue

phpMyAdmin running on CentOS 7 LAMP server shows following warning after logging in:

The secret passphrase in configuration (blowfish_secret) is too short.

 

 

Resolution

Open /etc/phpMyAdmin/config.inc.php file and look for following code (around line 14):

$cfg['blowfish_secret'] = '84657495123845128452'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

Replace the secret with a random string that is at least 32 characters long:

$cfg['blowfish_secret'] = 'P5DS+radU0TOqI7HX$cH!eb3zwnDDoDr'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

Log off and log back on again to phpMyAdmin and the warning should be gone.
