Authy requires a phone number, which you may or may not want to give out, but it also lets that phone number restore backups, so it’s vulnerable to SIM swaps.
Also it’s ugly and super high latency to navigate, but that’s just my opinion.

Without the backup password, you won't be able to restore a backup.
Can I import my OTPs from Authy?
You would only need to edit/export the "secret" and copy/paste it to Obsidian, in case they allow it.
