I try to compartmentalize my browsing habits. I use two browsers, one exclusively for logins and the other for casual browsing. Vanadium exclusively for logins (shopping, banking, taxes, etc.) and Bromite for everything else.
In Vanadium, all browser settings are default except custom DNS set as Adguard DoH and Disable JIT set to On.
In Bromite, all browser settings are default except always-incognito and custom DNS set as Quad9 DoH.
So the other day I used Vanadium to create another Google account just for logging Youtube history in SmartTubeNext on my Firestick. After account creation I wanted to secure the account with TOTP, but the option for authenticator was not present as it knew I am on a Pixel 4a and it wanted me to use the phone as the 2FA security key. I didn't want to do that, so I switched over to Bromite and logged in to Google to try and secure my account. Low and behold, the option to secure my account with authenticator was present and I was able to add the code to Aegis.
So how does Bromite mitigate fingerprints? I noticed in 'About Bromite' the phone user agent is set as SAMSUNG SM-G960U which is a Samsung Galaxy S9. Could it have been just that, or is there more to fingerprint mitigation in Bromite?
