Bitwarden has an excellent built-in password generator. If you're already a Bitwarden user, it's the natural choice — it generates and saves the password in one step. But what if you're not using Bitwarden, or you need a standalone generator you can share with someone who doesn't use a password manager?
This post compares Bitwarden's password generator with Ultimate Tools Password Generator — a browser-based option that requires no account and no extension.
What Bitwarden's generator offers
Bitwarden's password generator is integrated into the vault. It generates passwords with configurable: length (5–128 characters), uppercase/lowercase, numbers, special characters, and minimum counts for each character type. It also has a passphrase mode (word-based passwords like correct-horse-battery-staple). All generation happens client-side within the Bitwarden app.
The generator is free — it's part of the free Bitwarden account.
Side-by-side comparison
| Feature | Bitwarden Generator | Ultimate Tools |
|---|---|---|
| Password generation | ✅ | ✅ |
| Passphrase mode | ✅ | ❌ |
| Custom length | ✅ (5–128) | ✅ |
| Uppercase/lowercase | ✅ | ✅ |
| Numbers | ✅ | ✅ |
| Special characters | ✅ | ✅ |
| Exclude similar chars | ✅ | ✅ |
| Entropy display | ❌ | ✅ |
| Save to vault | ✅ (integrated) | ❌ |
| Account required | ✅ | ❌ Never |
| Extension required | Optional (web vault works) | ❌ |
| Browser-only (no server) | ✅ | ✅ |
| Shareable link | ❌ | ✅ (the tool URL) |
How both generators work under the hood
Both use cryptographically secure random number generation:
- Bitwarden uses the Web Crypto API (
crypto.getRandomValues) - Ultimate Tools uses the same Web Crypto API
The core algorithm is the same: pull cryptographically random bytes, use them to select characters from the allowed set. Neither sends data to a server. Neither is weaker than the other from a cryptographic standpoint.
Where Bitwarden wins
Passphrase generation — Bitwarden can generate passphrases like correct-horse-battery-staple — random words from a wordlist separated by a character. These are long but memorable. Ultimate Tools doesn't include passphrase generation.
Integrated save — Bitwarden generates and immediately offers to save the password to your vault. There's no separate copy-paste step. For Bitwarden users, this integration is the main advantage.
History — Bitwarden keeps a password history so you can retrieve recently generated passwords.
Where Ultimate Tools wins
No account — If you're helping a colleague set up accounts and they don't have Bitwarden, pointing them to a URL is easier than asking them to create a Bitwarden account. Ultimate Tools requires nothing — open the page, generate, copy.
Entropy display — Ultimate Tools shows the entropy in bits for the generated password, giving a concrete measure of strength. Bitwarden doesn't display entropy directly (it shows a "strong/weak" label).
No extension dependency — Bitwarden's browser extension is optional (the web vault works without it), but some corporate IT environments block browser extensions. A plain web tool has fewer compatibility issues.
Which to use
Use Bitwarden's generator if:
- You're a Bitwarden user and want to save the password immediately
- You need passphrase mode
- You want password generation history
Use Ultimate Tools if:
- You don't have a Bitwarden account and don't want to create one
- You need a generator you can share with someone via a simple URL
- You want to see entropy bits for the generated password
- You're on a device where browser extensions aren't available
Both tools produce cryptographically strong passwords. The choice comes down to whether you're inside the Bitwarden ecosystem or need something that works without any account.
