What is credential theft?

Credential theft steals authentication information: usernames, passwords, **API** keys, and session tokens. Attackers use stolen credentials to access accounts, impersonate victims, and enable further attacks.

Email-based **credential theft** typically uses **phishing**: fake login pages capturing entered credentials. Other methods include: **malware** keyloggers, man-in-the-middle attacks on login pages, and data breaches exposing stored credentials.

Impact extends beyond immediate access. Credential reuse means stolen passwords may work across multiple services. A compromised email password can enable: **account takeover**, further **phishing**, identity theft, and financial fraud.
