Wordlist | 6 Digit Otp

Assume that attackers possess every possible wordlist—from the full 1,000,000 entries to the top 100 most common. Build your defenses around rate limiting, short expiration, and cryptographic randomness.

2.1 The Keyspace A 6-digit numerical password has a fixed length $L=6$ using digits $0-9$. The total keyspace ($K$) is calculated as: $$K = 10^6 = 1,000,000 \text possible combinations.$$ 6 digit otp wordlist

A 6-digit OTP wordlist is only effective against systems with the following flaws: One-time passwords (OTP) - Security - MDN Web Docs The total keyspace ($K$) is calculated as: $$K

An attacker writes a script that submits login attempts to a website or API, cycling through a wordlist of 10,000 high-probability OTPs. Without rate limiting, a 10,000-attempt attack can finish in seconds. Copied to clipboard
