Why a strong, unique password matters
Weak or reused passwords are the single biggest cause of account takeovers. When one site is breached, attackers try the same email and password everywhere else. A long, random password that you never reuse stops that chain cold.
This pairs perfectly with a temporary email: when you create a throwaway account with a disposable address, give it a one-off random password too, so a leak from that low-trust site can never reach the accounts you actually care about.
- Use at least 16 characters for important accounts.
- Mix uppercase, lowercase, numbers and symbols.
- Never reuse a password across two sites.
- Store passwords in a password manager, not a notebook.
