Suggestion: be able to link Phoenix with web services like web wallets or browser extensions

[bitcoinuser]

Hi,

In these past days I was using a lot the Bottle.li custodial lightning wallet, when I was told that the service will be closed because government regulations (https://bottlepay.helpscoutdocs.com/article/40-official-announcement-on-the-shutdown-of-bottle-pay). So I started to think if will be possible to run a non custodial wallet on my phone and be able to securely link this wallet with a web site or a browser extension, so that I could use these services or extensions without need to manually interact with my phone.

How I think this could work:

1- I open a site like bottle.li and inside the site have an option to add an account (Add Phoenix Wallet).
2- When I click on add Phoenix wallet, will appear a field or qrcode with a unique id.
3- I open Phoenix wallet and scan this qrcode.
4- Phoenix show a message like: Bottle.li wallet wants permission to have access to your Phoenix wallet.
5- User can customize on Phoenix the kind of access, like: Bottle.li only will be able to spend 1000 satoshis per day.
6- Bottle is linked to Phoenix successfully.
7- When the user enter on Bottle page, Bottle will try to synchronize with Phoenix in this way:
7.1. Phoenix app will automatically open without human action on phone using the Google FCM.
Obs. I see it's possible to automatically open an android app when notification is received, as you can see here: https://stackoverflow.com/questions/54922694/is-it-possible-to-automatically-open-an-apps-activity-from-push-notification-in

Hello, thanks for the suggestion.

The main issue would be that the wallet should most of the time be locked behind a PIN/biometric, so even if your service can start Phoenix remotely, the user would still have to unlock the wallet himself.

There are also security issues with allowing a remote service access your money and spend it without any user input.

So it would require quite a lot of work, and even then I don't think you can avoid manual user input (and I'm not sure it would be a great idea either). Still, a more seamless interaction between the wallet and external services would be very nice!
