Struct PinConfig 

pub struct PinConfig {
    pub enforcement: PinEnforcement,
    pub min_length: u8,
    pub max_retries: u8,
    pub max_uv_retries: u8,
    pub auto_lock_timeout: u32,
}

PIN configuration

Fields

enforcement: PinEnforcement

PIN enforcement policy when PIN is set:

• “never”: Always use notification fallback (backward compatible, convenience)
• “optional”: Use PIN only when always_uv=true or client requests UV
• “required”: Always require PIN when set (most secure)

min_length: u8

Minimum PIN length in characters (CTAP spec: 4-63)

max_retries: u8

Maximum PIN retry attempts before lockout (CTAP spec: 8)

max_uv_retries: u8

Maximum user verification retry attempts before UV is blocked (default: 8)

This controls how many consecutive UV failures are allowed before UV is blocked. Use passless client pin uv-reset to restore the retry counter after authentication. Higher values improve usability but may reduce security against brute-force attacks.

auto_lock_timeout: u32

Auto-lock timeout in seconds after max failed attempts (0 = disabled) After lockout, authenticator must be reset to use PIN again
