How to Generate Strong Passwords Safely
Strong passwords are long, random, unique, and stored in a password manager rather than reused or memorized everywhere.

Length and entropy
Password strength is mostly about how hard the password is to guess. Long random passwords usually beat short complex-looking passwords because length increases the search space dramatically.
A 20-character random password from a broad character set is suitable for many everyday account workflows, provided it is unique and stored safely.
Randomness matters
Do not build security-sensitive passwords with predictable patterns, dates, keyboard walks, or ordinary pseudo-random helpers. Browser implementations should use cryptographic randomness such as crypto.getRandomValues.
Character sets and usability
Uppercase, lowercase, numbers, and symbols can all add search space. Usability still matters: if a password must be typed manually, avoiding ambiguous characters such as O/0 or l/1 can reduce mistakes.
Use a password manager
Random passwords are strongest when they are unique per account. A password manager makes that practical by storing long values you should not try to memorize.
- Do not reuse passwords across services.
- Copy generated passwords into a trusted password manager.
- Prefer multi-factor authentication for important accounts.
- Do not store generated passwords in screenshots, chat logs, or tickets.
FAQ
Is a longer password always better?
Length helps, but it should be combined with randomness and uniqueness. A long reused password is still risky.
Does DevPouch store generated passwords?
No. The password tool is designed to generate values locally and does not store them.
