Generate strong passwords and hashes offline

Account setup flows still ask for “strong passwords.” Browser-generated randomness is a solid default when you do not want a cloud password manager for a throwaway sandbox — or when you need a quick unique string while offline.

Passwords you can trust more

Open Password Generator and choose length and character sets that match the site’s rules. Longer is usually better than clever substitutions. Copy once into your password manager, then clear the page.

UUIDs for fixtures and APIs

UUID Generator creates version-4 IDs for test data, client-side keys, and demos. Generating them locally avoids leaking your internal naming schemes through a hosted generator’s logs.

Checksums and hashes

Hash Generator computes MD5 and SHA digests in the tab. Use hashes to verify a downloaded file matches a published checksum, or to fingerprint a string during debugging. Remember: hashing is not encryption, and MD5 is fine for checksums but not for password storage.

Encoding helpers

When you need to embed binary-ish text in configs, Base64 Encode / Decode stays client-side too.

Security basics

• Never reuse production passwords in screenshots or blog drafts.
• Prefer a dedicated password manager for accounts that matter.
• Treat hashes of secrets as sensitive if the input was sensitive.
