Anti-phishing identifier to emails

Introduce a anti-phishing phrase for all emails which will uniquely identify the Bitwarden service provider and your account.

Binance has this feature where you introduce a specific phrase into the account settings, and then this phrase will then appear in all Binance communication emails:

Pros:

  • control is given to the user
  • should be easy to implement (store the phrase with account settings, 0 trust compatible)
  • makes phishing almost impossible

Cons:

  • use devs coding time

This sounds like an interesting idea.

So, that is a “static phrase”, right?

I also think it’s an interesting idea in general.

But a “static phrase” could itself get phished or otherwise “stolen” by malware (probably not in your BW account itself, but in your emails then).

There is a feature called BIMI that is supposed to make it easier for a user to verify email authenticity

My understanding is email programs (like gmail) won’t display the logo in that position unless the full suite of dmarc/dkim/spf checks is configured in the most secure way, and they all pass. Many messages that will make it through the spam filter won’t meet the requirements for displaying a bimi logo.

Unfortunately, Bitwarden notification emails don’t always pass DKIM…

yep, it could, although this is a step away from no phishing protection.
It’s not a bullet proof solution but compared to how easy it is to implement, it’s a good one imho.

There is a way to accomplish this today… plus-addressed email. Most email providers allow you to append a plus sign followed by an arbitrary string to your name, for example,

[email protected]

If you use a plussed-address email address exclusively for Bitwarden, it can serve as the equivalent of an anti-phishing identifier.

The complication is that you will also need to login to your vault using the plussed-address.

I think it’s effortless to add a piece of dynamic text to an email.
