Enum PasswordLoginError 

pub enum PasswordLoginError {
    InvalidUsernameOrPassword,
    PasswordAuthenticationDataDerivation(MasterPasswordError),
    Unknown(String),
}

Errors that can occur during password-based login.

This enum covers errors specific to the password authentication flow, including credential validation, KDF processing, and API communication errors.

Variants

InvalidUsernameOrPassword

The username (email) or password provided was invalid.

This error is returned by the server when:

• The email address doesn’t exist in the system
• The master password hash doesn’t match the stored hash

Note

For security reasons, the server doesn’t distinguish between “user not found” and “wrong password” to prevent user enumeration attacks.

PasswordAuthenticationDataDerivation(MasterPasswordError)

Failed to derive master password authentication data from the provided password and KDF settings.

This error can occur during local cryptographic processing before the API call when:

• The KDF parameters are invalid (e.g., iterations below minimum threshold)
• The KDF algorithm is unsupported or corrupted
• Memory allocation fails during Argon2id processing

Unknown(String)

An unknown or unexpected error occurred during login.

This variant captures errors that don’t fit other categories, including:

• Unexpected OAuth2 error codes from the server
• Network errors (timeouts, connection refused, DNS failures)
• Malformed server responses
• Future error types not yet handled by this SDK version

The contained string provides details about what went wrong.

Forward Compatibility

This variant ensures the SDK can handle new error types introduced by the server without breaking existing client code.
