Keep in mind this is in the context of Authy sunsetting their desktop app, so I’ll compare to that.
Presently on desktop, if something requests a TOTP, I open up my Authy desktop app, can immediately identify the key I need (as the list is exclusively for TOTPs), I click it, and can click to immediately copy the TOTP as needed. I do not need to enter any search, the most I ever have to do (rarely) is scroll down slightly, since it’s a much more condensed list. I have maybe 15 accounts that use TOTPs that I have on Authy.
With Bitwarden’s desktop app, presently I have to open the app, and first need to search for the relevant account that has the TOTP. I have well over 100 passwords stored, and I have to search through them to find the ones that also have TOTPs attached. Usually this will involve typing in the name in the search bar, which is where the majority of the slowdown comes from. Additionally, I have to select the account first before the TOTP becomes copyable, and the key is present in a list of other pieces of other sign-in information.
I can mitigate the search by putting accounts with TOTPs to their own list, but accounts can only be put in one list at a time, so it’s at the expense of other forms of organization.
If every account I had used a TOTP, then the search functionality would need to be used more in Authy as well, but not every service has 2FA or even is significant enough to warrant it.
On the mobile Bitwarden app, however, I don’t have to utilize the search function as I can just click the the “TOTP” list button. Additionally, the codes are present immediately without needing to pull up the full item details, and can be copied directly. This is fantastically designed and I’d love to see it carried over to the desktop app; unfortunately, this is limited to the mobile app, so a copy-paste functionality doesn’t carry over to PC. Plus, I specifically want to use the desktop app so I don’t need to wake/unlock my phone every time.
Additionally, I want to stress that not all accounts where you sign in are done via browsers, so Bitwarden’s auto-fill in via the extension won’t work. Anything that has its own launcher or portal requires you to pull up the information manually. I can understand this feature being less useful on the browser extension, since in that case you can just use auto-fill, but that’s why I’d like to see it on the desktop app, where it’d speed up sign-ins on other applications and auto fill isn’t an option.
