Requests expire and are purged from the database every 15 minutes if they aren't approved or denied. ª - Auth-request public and private keys are uniquely generated for each passwordless login request and only exist for as long as the request does. The initiating client then uses the access code and fulfilled authentication request to authenticate the user with the Bitwarden Identity service. The initiating client then locally decrypts the master key and master password hash using the auth-request private key.
The initiating client GETs the encrypted master key and encrypted master password hash. The approving client then PUTs the encrypted master key and encrypted master password hash to the Authentication Request record and marks the request fulfilled. Listed below are examples of the data that is encrypted, as well as download links demonstrating the encrypted data.
Bitwarden is a zero knowledge encryption solution, meaning you are the only party with access to your key and the ability to decrypt the vault data. When the request is approved, the approving client encrypts the account's master key and master password hash using the auth-request public key enclosed in the request. Vault data can only be decrypted using a key derived from your master password. Registered devices, meaning mobile or desktop apps that are logged in and have a device-specific GUID stored in the Bitwarden database, are provided the request. The initiating client POSTs a request, which includes the account email address, a unique auth-request public keyª, and an access code, to an Authentication Request table in the Bitwarden database. Would greatly appreciate any help, as I'd prefer not to have to reset literally every password for every online account I use.When logging in with a device is initiated: I realize that what I'm asking is for someone to explain the security vulnerabilities of BitWarden, but also my understanding is that since this project is open source the vulnerabilities are well known amongst the cybersecurity and within the realm of acceptable risk. Is there a way for me to try to access the vault without pinging the server? The server response time makes a brute force attempt via the internet close to impossible, but if I were able to attempt it locally I think it would be possible. I know the schema for my password which will help me reduce the complexity of a brute force attack considerably. I migrated over from LastPass which has a way to reset your master password and didn't realize that wasn't an option with this software. Like many morons before me, I have accidentally locked myself out of my bitwarden account and have completely forgotten my master password.
