I need to save some passwords used on my app, so the user doesn't have to input them so often.
I'm trying to understand how this is done. I imagine to keep them safe they should be encrypted however my doubt is whether the user would have to input a "master password" to retrieve stored passwords which would kinda defeat the purpose of "remembering" them.
Can my app retrieve the passwords without the user needing to write a master password? How is this done?
