How Keeper Protects Against Brute Force Attacks on Password Manager Device Registration
Password managers are among the most helpful security tools available, offering strong password generation and encrypted credential storage. However, attackers are beginning to target password managers by exploiting the device registration flow, which is the process used to verify and approve a new device before it can access a user’s vault. By brute-forcing the One-Time Passwords (OTPs) that protect this step, attackers can register unauthorized devices and download copies of encrypted vaults.
