You can set a new Hivesigner password if you forgot the previous one. I've done it before.

Hive Keychain mobile app has it's in-app browser.

Then I need to try changing and see what happens. I have hive keychain app, don't know about the browser, how do I get to know that please?

You can use it to access or sign in to any of the frontends of Hive, even Leodex, etc.

I'm currently traveling and it's not easy to do things on mobile, lol!
