Feature Request: enhance "sign-in" to support external wallets (e.g. Meta Mask / Trezor / Ledger).

[snodnipper]

Supporting external wallets should minimise the onboarding experience to (1) accept terms and conditions (2) type pin on external wallet (3) exchange.

External hardware wallets allow folks to maintain good levels of security even on potentially compromised computers, which increases confidence in using online systems.

The Kyber decentralised exchange is a great example:

The Kyber web wallet source code is on github. Searching for, say, Trezor shows that they are using the Trezor Connect software.

Furthermore, webauthn is being developed to help standardise Trusted Platform Modules (TPMs) / Secure Elements (SEs) in web-browsers - where we might expect reduced development overhead in the future.

It would be great if BitShares had a similar experience to Kyber.

Further development of https://github.com/bitshares/bitshares-ui/issues/895.

@sschiessl-bcp / @startailcoon Should we contemplate this or will the same through Beet be enough (Beet support for HW wallets is planned as it becomes available)

[sschiessl-bcp]

I'm in favor of allowing external sign ins.

Two tasks:

• allow external service, or user, to define an account name to be logged in with, without giving credentials
• refer all calls that need private key access to external service

Does not matter if its Beet or some other programm for the general framework
