But I don’t see it, I did notice that the Authenticator Key entered on the left is much shorter than the one that is generated from my WordPress Two-Factor plugin.
Is this the reason why it isn’t working for me?
I scanned the QR code, logged off of my WordPress account, logged back in, entered in the TOTP code generated by the Authy app and can confirm that the Authentication Code works.
No problem, both those images were pulled from public information. The first image is from Bitwarden’s site itself, I just circled the TOTP code. The second was directly from the WordPress plugin’s page.
Yes, that’s what I did (for my actual Authenticator Key).
To get Bitwarden to generate TOTP codes three things are needed
a subscription - free versions can store the string but will not generate codes
the (correct for the website) string stored in the Authenticator Key field
the device’s clock being correct (best to have it set by a time source every day or two)
With these things it will generate the right codes. You can check by putting the same information into any other TOTP generator, when you will see them generating the same sequence of codes and they will change at the same time (within limits, I have seen a variation of up to about a second).
