A couple years ago you could replace that with Apple (except for the ads part i think), does that still apply or has apple seen any kind of redemption?

I’m probably an ignorant paranoid about them, I know I should google a bit of them, but instead I’m going for the ol’ trusty ask the community.

Do they save your passwords locally or in the cloud? If locally, what if I want to sign in in another device? What if I lose the device I have my passwords on? What if they hack my device? If in the cloud: How can I know the service is not stealing my information? If I can access it anywhere, wouldn’t that mean it also needs a password? Wouldn’t that make it twice as unsafe as it would only take one password to access the rest?

Edit: Damn, I got extremely useful answers, I’m starting to like lemmy!
