In MySQL, a user is allowed to have a PROXY user. This means that a user can behave the same way as the original user with the same permissions as the original user.
Granting PROXY Access
GRANT PROXY ON original_user TO proxy_user
Revoking PROXY Access
REVOKE PROXY ON original_user FROM proxy_user
In both of the cases above, original_user is the user for which a PROXY is allowed. The proxy_user can imitate all permissions of the original_user.
PS: There could be specific changes in the way the commands are used based on the levels of permissions that you have.
