I have the same or similar problem on my samsung android phone. When trying to sign into Bitwarden 2FV comes up and sends code to my email but I never can find the email with the code that was sent. However when I signed into www.bitwarden.com and they asked for 2FV. I was able to find the email with the code. May need a different password program.
Welcome, @Mike_Crandall to the community!
You might consider setting up a two-step login method. Notably TOTP and yubikey are much more reliable than New-Device-Login-Protection, which is what one gets if they don’t have anything better set up.
That would be great but I can’t open Bitwarden on my phone, I can never find the email with the code to ooen Bitwarden. I even deleted Bitwarden on my mobile but I have to use 2FV to setup Bitwarden. I do have Bitwarden on my laptop. It does not have 2FV setup. I won’t set it up and possibly get locked out there too. Mike
You may have a misconception of how Bitwarden works. Security settings, such as 2FV, once configured, do apply universally to all devices, apps, browser extensions, etc., that you use to access your Bitwarden vault. Thus, if you are required to use 2FV to login to the Bitwarden mobile app and Web Vault, then you will also be required to use 2FV when logging in to the Bitwarden desktop app or a Bitwarden browser extension on your laptop computer. The only exception is if you have enabled the “remember me” option when logging in, in which case the 2FV requirement will be waived for that specific app or extension, on that specific device only (and for a maximum of 30 days).
Similarly, if the verification codes that you are talking about are not actually 2FV (i.e., Two-Step Login using email codes), but are codes requested by the “New Device Login Protection” feature (which is enforced by default for users who have not enabled 2FV), then the code will be required for every device and app/extension that is not recognized by the Bitwarden server. Because Bitwarden uses a unique code stored on your local devices to identify each Bitwarden app or browser extension where you have previously logged in (and hence exempt from the New Device Login Protection verification), if this piece of data is ever lost (perhaps during an operating system update or a Bitwarden software update), then the server will again ask for a verification code when you log in.
All of this is just to say that you should not get too comfortable with your ability to use Bitwarden on your laptop without needing a verification code. It is possible that your laptop will also start asking you for codes at some point in the future. Therefore, it would behoove you to ensure that you will be able to reliably access your Bitwarden account in the future.
To set up two-step login using a TOTP authenticator or a Yubikey (as suggested by @DenBesten above), you do not need to open Bitwarden on your phone. You did say that you were able to successfully sign in to the Web Vault (vault.bitwarden.com or www.bitwarden.com) using the email codes. That is what you should do, and then use the left-hand navigation menu to open Settings → Security, after which you should click the tab labeled “Two-Step Login” at the top of the Security window. From there, follow the instructions in the link that was posted by @DenBesten.
@Mike_Crandall I now moved this discussion into a separate topic as the issue here seems to have been the “New Device Login Protection” (and not “email-2FA”).
