I suggest keeping Nostr's identity and money separate. nos2x works well.

Could you share your reasoning behind this suggestion?
Put eggs in different baskets, and use specialized tools
Which key management tool do you use and recommend for browsers on Android? Nos2x is great for browsers on desktop and Amber for Android apps.
On Android I use Amber.
Another insteresting solution is nsec.app, if apps support NIP-46.
Wasn't aware that Amber detects and works with websites as well, not just native apps. Just now saw that it does on https://nostrudel.ninja/#/signin/. That's great!
