Remove Administrator as Technician, but still able to log on to make configuration changes?

I have 2 technician licenses and 2 technicians which i would like to give them their own username to logon without administrator rights, then there is me as an administrator who would use the administrator logon for configuration changes.  

Is it possible to delete the administrator account from the technicians list but still logon on as administrator, ive searched here and found that you can remove the administrator from the technician list, which is great but in doing this, would i still be able to log on as username administrator to make all the configuration changes, or if deleting the technician also removes this log on?
i hope that makes sense.
