Samsung G6 Tethering Hotspot Password Says INCORRECT on Joining Devices

New AT&T customer 4/2015. Enabling hotspot on G6 and tethering other devices (iPad) worked previously. I rarely use this feature but now when attempting to connect a device after entering the supplied password the device reports 'Incorrect Password Entered.' Anyone in this community have suggestions before I brave asking for help in a store? Thanks.
