how to reauthenticates sec/suddenlink

Not knowing what your setup is, my best advice would be to logout and try logging in again. If it is not authenticated, you should be prompted to do so.

If you’re using a computer, you might try clearing your cookies, but beware that will clear any of your saved passwords.

Appreciate your response

I have to do it on all my devices every time,whether at work on my tablet or my phone .Log out and log in

I tried logginh out then back in but that didn’t work either.

Turn it off, and then re-start/re-boot your device. I have to re-authenticate every time on my phone to Chromecast it to my TV, pain in the rear.
