why do you need to use alby (ugh) or nos2x? I have alby— I’m being stubborn & don’t want to use it.

why can’t I use my nsec on my phone or is that what nos2x is for— I don’t use a desk top for Nostr unfortunately. Probably need to fix that.
Yeahh I have the same problem since I'm always on mobile nostr. Some developers are really strict about security, so they only allow access via those extensions that obscure your nsec. It's kind of a pain, but I guess I get it.
I’m grateful they think about security. Maybe time to shop for a new lap top.
and thanks for this link! Saving it for later!
