Accounts where TOTP code should be appended (or prepended) to the password

1P_Evon The issue with that—at least with the current version of 1Password on iOS (8.10.56)—is that 1Password will autofill the password field, and also submit the login form at the same time it copies the OTP code to the clipboard. This results in the password field becoming reset due to the submitted password being incorrect. So you never get a chance to prepend the copied OTP code to the auto-filled password before the login form gets auto-submitted.

In which case, you'd need to manually switch back to the 1Password app, copy the OTP field, switch back to Safari, paste in the code, then switch back to 1Password, copy the Password field, switch back to Safari, tap the password field, try to manually move the cursor to the end of the previously entered OTP code, long press to bring up the "Paste" option, tap on "Paste", then tap on the "Login"button.

Oh, and you have to make sure that you do all of this before the TOTP code expires. And you also have to completely disable the Autofill feature in the iOS settings, which severely limits the convenience of using 1Password on iOS.

So I effectively cannot login to my OPNsense router on iOS unless I either completely disable Autofill, or if I insecurely manually concatenate the OTP and static Password in a notes app or something via copy paste from the 1Password app, then manually copy/pasting the concatenated password back into the Safari password field. And again, trying to do this all before the OTP code expires.
