Eclipse and github personal access tokens

When I update eclipse or delete it or something, it gets into a state of being unable to save to secure storage. When I push to github it won't save the personal access token so I have to regenerate it. Next time I restart eclipse I have to generate it again.

Dear future Jim, the solution today was found in stackoverflow:
In eclipse,

Preferences > General > Security > Secure Storage > Contents

and delete either everything, or at least the part for github.
