been doing this as well, need native apps that support signers, my nsec is valuable!
Discussion
Most apps already support NIP46 remote signing, the ones that don't are at this point not worth giving your main nsec
Which mobile clients support this?
You mean mobile webapps or native apps?
Native.
Amethyst and Yana that I know of. But those support Amber natively (offline) without the need for NIP46 remote signing, since the apps are on the same device.
The real benefit is that you can sign in to mobile and desktop webapps (on the same or different devices) using Amber's NIP46 signer.
