Best way to store sensitive information

Ionic Framework ionic-v3
1

Trying to make our app user friendly. We want to somehow remember the users login name, that way they don’t have to type it in everytime.

Local storage is a no no. Session storage kind of defeats the purpose. I guess cookies could be an option.

I know about https://ionicframework.com/docs/storage/ But we do have a browser version. Would that work with the browser? Is there much overhead using this ionic storage?

What is the best way to store user data?

Yes, Ionic Storage has several backends, some of which work in browsers. I’m a bit concerned about the disconnect between your headline (“sensitive information”) and what you say in the post (“user’s login name”). I wouldn’t consider a login name “sensitive information”, but if you’re really wanting to store passwords, or something that actually is sensitive, the answer is, in large red flashing letters, DON’T.
