Use this article to disable your mods (regain admincp access) https://vborg.vbsupport.ru/showthread.php?t=259619 *Simply add the disable hooks code at the top of config first, then follow other info if that does not restore admincp access first.

*You may also need to temporarily rename .htaccess to .htaccess1 or similar if login issues still persist after disabling hooks.

As for the vbseo password, if it was a newer version of vbseo then find the config file and edit it - the config.xml is located in: /vbseo/resources/xml/config.xml

Find the lines:

<setting>
<name>VBSEO_ADMIN_PASSWORD</name>
<value>635182cbab83bcdg50a83993c933r4bf</value>
</setting>
<setting>

The <value>#######</value> will be different than the above, that is the encrypted password. Simply remove it as shown:

<setting>
<name>VBSEO_ADMIN_PASSWORD</name>
<value></value>
</setting>
<setting>

*Save the file, re-upload the config.xml file. Now when you return to access the vBSEO control panel it will no longer require a password to access but instead ask you to enter in a new password instead . Once you're done don't forget to chmod the config.xml back to 644 instead of 777 so it's "secured" although to be honest vBSEO is no long secure, you should revert and use mod rewrite friendly url's within vBulletin 4 or switch to DBSEO (if you switch from vBSEO to DBSEO be sure you do not uninstall vBSEO until DBSEO is installed and all links work as they did prior, once you confirm DBSEO works as you wish then uninstall vBSEO).
