It’s right there under New. I’m not sure how long it has been there!
Unfortunately it doesn’t appear to let you change any parameters, so you’re “stuck” with ed25519.
You also can’t paste in an existing key, which is what I was expecting to be able to do.
I don’t have it available in my extension or desktop app. I just downloaded the latest flatpak, but forgot to check versions in the flatpak and firefox extension
A link somebody else posted says it’s not in the flatpak yet.
Looks like maybe the import is in the desktop app only, as I can’t see it in the extension or the web vault.
