How to Create a Strong Random Password
Practical password length, character set, entropy, and password manager guidance without exaggerated security claims.
Prioritize length and uniqueness
Use a long, randomly generated password that is unique to one account. Reusing a strong password still creates risk if another service is breached.
Choose compatible character settings
Use uppercase letters, lowercase letters, numbers, and symbols when the account accepts them. Excluding similar-looking characters can make a password easier to enter manually without making it memorable.
Store it safely
Copy the result into a trusted password manager and avoid saving passwords in chat messages, screenshots, shared documents, or source code. Enable multi-factor authentication where the service offers it.
