1Password allows one to add any item to Apple Watch, also secret notes, memberships etc. It would be nice to allow more types of data unto Apple Watch than only 2FA TOTP codes. Can be useful if your phone is not worn, stolen or out of battery.
Hypothetical scenario:
I’m not using my computer or phone. I only have my watch with me.
I’m unable to log in because I only have TOTP codes (my passwords are unpronounceable messes of symbols).
However, if I have my phone with me, I have both TOTP codes and passwords stored in the phone.
What is a realistic scenario where I can only use TOTP codes from watch?
In essence, this is a soft feature request for more data storage in the watch.
@vonProteus Welcome to the forum!
I moved your request into an existing feature request to the same topic.
So it looks like we won’t get this feature anytime soon 
I recently switched from Enpass and the only feature I really miss is to be able to store (selected) passwords to the Apple Watch, not only the TOTP codes.
