"but it also lets that phone number restore backups" - is this true? I use Authy and can use a phone number to connect a new device to my account, but to restore access to credentials on the new device I need to enter a passphrase. I don't think there's a way to restore credentials with just a phone number, but will need to check.

Edit: the following article appears to confirm my beliefs: https://support.authy.com/hc/en-us/articles/360036580453-Rec...

Without the backup password, you won't be able to restore a backup.

You can disable the multi-device capability of Authy to lock it to a specific set of devices e.g. primary and a backup burner if that's your thing.

Yep, I can add that backups in Obsidian are automatically managed and stored on the iCloud Keychain, hence accessible just by using the app on any device

Just yesterday I thought it’d be great if Authy used iCloud instead of their own backend for storage. Thank you for building this.

Can I import my OTPs from Authy?

I haven't been using Authy for years, last time I checked there was no easy way to export data from it (they want to keep you tieeeed!), but hopefully things have changed.

You would only need to edit/export the "secret" and copy/paste it to Obsidian, in case they allow it.
