Android PWAs, or Preferably Browsers, and their cookies

I want to use websites installed as apps or kept as tabs in my browser for my many log ins. If i sign into X, Reddit, Claude, and other sites, are they all isolated in Vanadium or Cromite? I believed that the cookie Google, Apple, and Facebook creates in “Sign in with Google/Apple/Facebook” option tracks you across all sites that use them. I do not want to install PWAs if I don’t have to since I like opening things in new tabs.

There are no mobile profile browsers and I am running out of browsers I trust to use like Brave. I do not want to install an app.

Is there anymore information I can find on this? I need clear and hard ‘proof’ not to mix log ins in the same browser.

Unless your cookies and other data gets cleared often for it to not matter.

I then recommend you change your browser settings such that your cookies and site data re cleared on every session so any cookies websites may store is highly temporary and for that session only. Or you can always manually clear everything each time.

Btw, for some things you may still want to consider installing as a PWA. They are a great way to compartmentalize a website that you don’t mind being always logged in. For example: I have Kagi Assistant installed as a web app. I don’t often use it but its handy and right there to use immediately for quick searches and I don’t have to keep loggin in everytime I clear my browser data.

I need a solution for all these sites that I can stay signed in full time.

Block third party cookies

It’s honestly as far as you will need

You want to stay signed in full time and yet you don’t want any cookie correlation. That’s almost impossible thought it would mostly depend on the website.

I think you’re asking for a very specific thing that I don’t think is possible at-least as you want it reading your post again.

PWA is the only way to go about it unless you install apps (which I know you said you don’t want to).

PWA isn’t an isolated browser profile though. Go make an X PWA and then on the same browser go to x.com, you will be signed in. Is what @GorujoCY said correct? It is simply that “sign in with Google" is everywhere and I do not need them to know X profile which could be connected to whatever social media.

After you make a PWA you want and sign into it. Delete all browser and site data of your browser and then check if you’re still logged into the PWA. I think you will be. Atleast this is how it works on iOS and it’s been a while I tried this on Android so I may not be accurate in my thinking or expectation here.

Try it out!

If you’re on Android, a PWA is no different than an open tab. It’s on the presentation that changes. Other PWA features will still work, like notifications and so on, even whether you “install” it or not. Sounds like it’s different on iOS.

It sounds like the real challenge in this case is that several services are tied to one login, whether it’s sign in with Google or something else. If that’s the case, then the long term solution is to give each of these accounts their own credentials and then they won’t be tied together anymore. From what I understand, the tab sandboxing that Chromium does will take care of the rest, no?

Hello, thank you for clarifying for the other commenter. All log ins are independent with their own burner emails, but I heard that the “sign in with Google" function tracks you across all sections even if you are not signed into Google. Would that only matter if I was signed into a Google account, which I do have for maps?

Sign in with Google means using your google account to sign into another service. As long as you don’t use that option, I think you should be fine. However, to be on the safe side, I personally would not even sign into google on the same browser. I would just use a different browser for Google sign ins.

Also, if you want cookies to be separate, have you thought about using Firefox containers in Firefox browser? This allows you for example to sign into two different X accounts using the same browser by making a container for each one. It’s designed specifically for that purpose.

I apologize if this doesn’t answer any of your questions correctly. I honestly had trouble understanding what you were wanting to do.

This is for my mobile phone, running GrapheneOS. I am running out of browsers to isolate my sites is the problem. I wish there was profiles or containers like desktop.

Hermit Browser by Chimbori might work for you. They allow you to isolate sites in their own containers.

I think to unlock all the features though you have to pay a one time fee.
