- On Keybase, create an HTML file in your
./public/directory (I choseproofs/mastodon.html) - Add the standard verification tag somewhere in the HTML, e.g.
<a rel="me" href="https://infosec.exchange/@tychotithonus">Mastodon</a>
- Navigate in the browser to the *raw* public view (username.keybase.pub) of the file (and you might want to view source to make sure that the “me” rel tag is there):
https://[keybase-username].keybase.pub/path/to/file.html
- Use that link as your Keybase link in your Mastodon profile.
A bit hack-y … but it works!
