I would love to see a feature that allows users to store their Nostr nsec keys from the Alby browser extension and sync them securely between the extension and Alby Go. Many users, including myself, were hoping for a way to keep our Nostr nsec keys on our mobile device in an Alby app. When Alby launched the mobile app Alby Go, I sensed some users were disappointed when there was no way to place their Nostr keys on it for safekeeping, just as they did with their browser extension.
It makes sense to think that if the browser extension is a wallet interface and a Nostr signer or safekeeping, Alby go that is also a wallet interface, would also become or have at some point a Nostr signer, or at least be a Nostr keys safekeeping on mobile.
The idea would be to have a secure option where Alby Go can "read" the nsec key from the browser extension and store it safely on the mobile app. This would simplify access to the Nostr nsec keys on our mobiles, making it unnecessary to transfer the key manually through methods like email or messaging apps. The Nostr nsec key could be kept just for safekeeping, no need for a full Nostr client, just easy access for quick copy-pasting when using other mobile Nostr apps.
This would make managing Nostr keys much more convenient and secure for those of us who use multiple devices and wants to safekeep the Nostr nsec key on our mobile as well, in addition to have it in our browser plugin.
