2026 has already produced some of the largest credential leaks on record. According to reporting from Time, researchers identified more than 16 billion login credentials exposed across multiple datasets, with access spanning major platforms including Apple, Google, Facebook, GitHub, and Telegram. Separately, TechCrunch’s mid-year roundup documented a publicly exposed database of 24 billion stolen credential records discovered in June, alongside major individual breaches at AT&T (73 million customers, including Social Security numbers) and Charter (40 million records).

Why a leak this size matters even if you weren’t directly breached

Large-scale credential dumps like this are frequently compiled from many older, smaller breaches combined together — known as “combo lists” — and are used in automated “credential stuffing” attacks that try leaked username/password pairs against other sites, betting that people reuse passwords across services. A password that was never part of the original leak can still be at risk if it’s identical to one that was.

What actually protects you

The single most effective defense against credential-stuffing attacks isn’t a more complex password — it’s a unique password for every account, so that a leak at one service can’t be used to access another. Length also matters more than forced complexity: current security guidance favors long, random passwords over short ones stuffed with symbols, since length increases the possible combinations far more effectively.

Generate a genuinely unique one

Our password generator creates long, cryptographically random passwords using your browser’s secure random number generator — ideal for giving every account its own unique credential rather than reusing one across services.
