Support non-default-browser SSO

### Your use case

#### What would you like to do?
I would like to perform SSO login without using my default browser
#### Why would you like to do it?
Because my default browser is a catch-all for untrusted applications who's target cannot be configured, and I do not wish to trust an untrusted session with a trusted login process.
#### How would you like to achieve it?
A button, label, or some other method of being provided the SSO link itself so that its single use can be performed on a browser of choice, rather than being consumed by a browser that cannot safely perform SSO.

### Have you considered any alternatives?

I have set up my default browser to refuse to resolve the SSO links, which permits me to copy them to the correct browser and continue the login process.

### Additional context

Most other services perform validation via email (which allows easy link copying) or they provide the link as text in addition to a button so that users can copy it if their default browser does not work for some reason, which is not uncommon among nontechnical users.
