Seems to be a bug between the BitWarden extension and a Vault that has 100000 KDF iterations. Feature function Allows admins to configure their organizations to comply with change in recommendations over time (as hash compute capabilities increase, so does the need for increasing KDF iterations). After changing that it logged me off everywhere. At our organization, we are set to use 100,000 KDF iterations. The title of the report is: "KDF max iterations is [sic] too low", hence why I asked what you felt a better max number would be, so if the issue is the min number, that's different. I had never heard of increasing only in increments of 50k until this thread. End of story. It has also changed. Iterations are chosen by the software developers. Remember FF 2022. Bitwarden Increases KDF iterations to 600k for new accounts and double-encrypts data at rest. 6. The feature will be opt-in, and should be available on the same page as the. Therefore, a. This is equivalent to the effect of increasing your master password entropy by 2 bits, because log2(2000000/500000) = log2(4) = 2. If I end up using argon2 would that be safer than PBKDF2 that is. Not sure if this is already on the @Quexten’s and Bitwarden devs’ list of things to do, but I think it would be very helpful to update the Interactive Cryptography Tool to include an implementation of the new Argon2 KDF Support (including the ability for users to test the settings for iterations, memory, and parallelism parameters). app:web-vault, cloud-default, app:all. json file (storing the copy in any. The KDF iterations increase the cracking time linearly, so 2,000,000 will take four times as long to crack (on average) than 500,000. Setting your KDF iterations too high could result in poor performance when logging into (and unlocking) Bitwarden on. The point of argon2 is to make low entropy master passwords hard to crack. Based on the totality of the evidence available to date (as summarized above), my best guess is that the master password hash stored in the cloud database became corrupted when you changed the KDF iterations. Argon2 (t=10, m=512MB, p=4) - 486. Feature function Allows admins to configure their organizations to comply with change in recommendations over time (as hash compute capabilities increase, so does the need for increasing KDF iterations). By the way, Sends (which I don’t really use) also have 100K fixed pbkdf2. The recent LastPass breach has put a lot of focus on the number of PBKDF2 hash iterations used to derive the decryption key for the password vault. With the ambiguity in some of the Bitwarden staff responses, it is difficult to say at this time what is going on. Consider Argon2 but it might not help if your. By the way, Sends (which I don’t really use) also have 100K fixed pbkdf2. log file somewhere safe). Do beware, Bitwarden puts a limit of 10 iteration rounds because in QA testing, it was unlimited, which lead to a tester having a 30 minute unlock time (1k+ iterations at 1GiB memory). By the way, Sends (which I don’t really use) also have 100K fixed pbkdf2. pub const CLIENT_KDF_ITER_DEFAULT: i32 = 5_000; Was wondering if there was a reason its set so low by default, and if it shouldn't be 100,000 like Bitwarden now uses for their default? Or possibly a configurable option like how PASSWORD_ITERATIONS is. The user probably. This seems like a delima for which Bitwarden should provide. Exploring applying this as the minimum KDF to all users. 512 (MB) Second, increase until 0. Ask the Community. Bitwarden has never crashed, none of the three main devices has ever slowed down when I started the Bitwarden Android app or web extension besides my other apps/programs. Bitwarden Increases KDF iterations to 600k for new accounts and double-encrypts data at rest. Increased default KDF iterations for PBKDF2: New Bitwarden accounts will use 600,000 KDF iterations for PBKDF2, as recommended by OWASP. With the warning of ### WARNING. Exploring applying this as the minimum KDF to all users. grb January 26, 2023, 3:43am 17. When you change the iteration count, you'll be logged out of all clients. The KDF iterations increase the cracking time linearly, so 2,000,000 will take four times as long to crack (on average) than 500,000. The hash credential to login to Bitwarden servers is only 1 PBKDF2 iteration from the vault master key. The hash credential to login to Bitwarden servers is only 1 PBKDF2 iteration from the vault master key. Can anybody maybe screenshot (if. Memory (m) = . If that is not insanely low compared to the default then wow. I went into my web vault and changed it to 1 million (simply added 0). If your original password is 50 bits of entropy, each additional bit is (theoretically) double as costly to crack. Not sure if this is already on the @Quexten’s and Bitwarden devs’ list of things to do, but I think it would be very helpful to update the Interactive Cryptography Tool to include an implementation of the new Argon2 KDF Support (including the ability for users to test the settings for iterations, memory, and parallelism parameters). The user probably wouldn’t even notice. Higher KDF iterations can help protect your master password from being brute forced by an attacker. Because the contents of this file are expunged if you ever log out (which can happen unexpectedly, if your session expires, if you change your master password or KDF iterations, if Bitwarden resets their servers, etc. Bitwarden Increases KDF iterations to 600k for new accounts and double-encrypts data at rest. Hacker NewsThe title of the report is: "KDF max iterations is [sic] too low", hence why I asked what you felt a better max number would be, so if the issue is the min number, that's different. My understanding is that a strong master password should still be secure even with a low number of KDF iterations, but for a product like a password manager, the bar should probably be higher than that. json file (storing the copy in any. But they don’t even store the kdf / iterations in the database, so changing it would require another database migration / backend change which I didn’t really feel like taking on considering how low the risk for a send is anyways. Bitwarden Increases KDF iterations to 600k for new accounts and double-encrypts data at rest.
