LastPass was once the undisputed king of password managers — 33 million users, the most polished interface, and years of trust built up. Then came the 2022 breach: attackers stole encrypted password vaults plus unencrypted metadata (URLs, usernames, billing info). Security researchers unanimously recommended leaving. Enter Bitwarden: open-source, zero-knowledge, free for core features, and never breached. How do they compare today?
LastPass's 2022 breach resulted in attackers obtaining encrypted password vaults. If you had a weak master password, those vaults can be brute-forced. Even with a strong master password, your site URLs and usernames were stolen unencrypted. This context is essential for any LastPass vs. Bitwarden comparison.
📋 In This Comparison
Security — The Most Important Factor
| Security Factor | LastPass | Bitwarden |
|---|---|---|
| Zero-knowledge encryption | ✓ Yes | ✓ Yes |
| Open-source code | ✗ Closed source | ✓ Fully open-source |
| Third-party security audits | ✗ Not published | ✓ Annual published audits |
| Major data breaches | ✗ 2015, 2022 (major) | ✓ None |
| Encryption algorithm | AES-256 | AES-256 + XChaCha20 |
| PBKDF2 iterations (2025) | 600,000 (raised after breach) | 600,000 (default) |
| Bug bounty program | ✓ Yes | ✓ Yes |
| Self-hosting option | ✗ No | ✓ Vaultwarden |
Security verdict: Bitwarden wins convincingly. The open-source codebase means any security researcher can audit Bitwarden's code. Combined with published annual audits, zero breach history, and a completely transparent encryption model, Bitwarden's security posture is substantially stronger than LastPass's — especially post-2022.
Pricing Comparison
| Plan | LastPass | Bitwarden |

| Teams (per user) | $4/user/month | $4/user/month |
| Enterprise (per user) | $6/user/month | $6/user/month |

Ease of Use — Where LastPass Still Has an Edge
We'll be honest: LastPass has a more polished, beginner-friendly interface. The onboarding experience is smoother, the browser extension is more visually refined, and the mobile apps feel more consumer-focused. Bitwarden has improved substantially and most users adapt quickly, but if you put a non-technical person in front of both, they'll probably find LastPass easier on day one.
That said, the UX gap has narrowed dramatically with Bitwarden's 2024 redesign. The autofill accuracy is now comparable, the browser extension has been rebuilt, and the mobile apps are genuinely good. Most users find Bitwarden's interface perfectly comfortable within a week.
The Free Tier — Bitwarden Wins Completely
LastPass's free tier restriction — one device type, either mobile OR desktop — makes it nearly unusable for most people in 2025 who use both a phone and a computer. Bitwarden Free gives you unlimited passwords, unlimited devices, and all the core features you need. This is the single most important difference for users who don't want to pay.
How to Switch from LastPass to Bitwarden
- Export from LastPass: Log in to LastPass.com → Advanced Options → Export → LastPass CSV File. Save the file.
- Create a Bitwarden account at bitwarden.com (free)
- Import to Bitwarden: Log in to vault.bitwarden.com → Tools → Import data → Select "LastPass (csv)" → Upload your file
- Verify the import: Check that all your passwords, usernames, and URLs transferred correctly
- Install Bitwarden extensions: Add the Bitwarden extension to all your browsers and disable the LastPass extension
- Set up Bitwarden on mobile: Download the Bitwarden app and set it as your autofill provider in your phone settings
- Delete the CSV file immediately after import — it contains all your passwords in plain text
- Cancel LastPass and delete your account
The whole process takes 15-20 minutes.
Verdict — Which Should You Choose?
Choose Bitwarden If:
- You want the strongest security track record
- You need a free option with no device restrictions
- You value open-source and transparency
- You use Linux or want a CLI tool
- You want to self-host your vault
- You're currently on LastPass (switch now)
LastPass Is Acceptable If:
- You're already a paying customer and don't want to migrate
- You specifically need the LastPass enterprise features
- You've changed your master password since 2022 to a strong passphrase
Our recommendation: Switch to Bitwarden. It's free, open-source, more secure, and has been shown to handle security issues transparently. The 2022 LastPass breach exposed that encrypted vaults can be stolen and targeted for offline brute-force attacks — a risk that simply doesn't exist with Bitwarden's track record. The migration takes 15 minutes and you'll never look back.
