Security, U2F keys, compatibility, etc.
I don't know who to trust for this information so I am asking here. If you can recommend a site or sites you trust and have confidence in, by all means let me know. I never heard about U2F keys until I found out today that Facebook supports it.
Does Safari and Mojave support U2F keys?
Where can I get a U2F key?
Can you recommend a good VPN?
Thanks,
Mindy
