Proton Pass vs LastPass: Privacy Comparison
Here we put Proton Pass head-to-head with LastPass across the six privacy factors that matter most: their data collection practices, encryption implementation, third-party data sharing, user privacy controls, transparency, and historical track record. While both products address similar requirements, the philosophies they bring to protecting users diverge sharply. Our assessment finds that Proton Pass provides a noticeably better overall privacy experience, although neither service is without trade-offs that deserve a careful, detailed look.
Bottom Line First
Before the dimension-by-dimension breakdown, here is the summary our scoring produced. Across the six privacy dimensions we score, Proton Pass finishes ahead of LastPass, 54/60 to 37/60. That total reflects a privacy comparison in which one service is consistently the more privacy-respecting choice, even though both cover the same functional ground.
The largest single-dimension gap is in Data Collection, where Proton Pass leads by 3 points -- Proton Pass 10/10 to LastPass 7/10. On Encryption the margin nearly vanishes: Proton Pass 10/10 against LastPass 8/10. Read on for the dimension-by-dimension reasoning behind these figures.
Data Collection Practices
Every privacy assessment starts with data collection. How much a service gathers, stores, and processes about its users is what ultimately drives the privacy risk of using it. Proton Pass takes a leaner approach here, capturing only the data strictly required to make the service work. Its rival pulls in a wider net of information -- behavioral patterns, device identifiers, and usage analytics that go well past what the core features actually need. Our marks were Proton Pass 10/10 and LastPass 7/10 in this area. What separates them is not merely how much is gathered but why it is gathered and whether it is truly needed.
Encryption Standards
Encryption guards user data as it moves and while it sits at rest, and how well it is built differs enormously from one service to the next. Proton Pass puts tougher encryption in place, with sturdier protocols shielding data in transit and stronger safeguards for what is stored. The two implementations part ways on coverage (which data actually gets encrypted), on strength (which algorithms and key lengths back it up), and on whether end-to-end encryption is in play (which keeps even the provider from reading user content). For encryption, Proton Pass scored 10/10 while LastPass scored 8/10.
Who Else Gets Your Data
How services share data with third parties is a critical privacy dimension. This includes sharing with advertising networks, analytics providers, business partners, and in response to government requests. Proton Pass maintains more restrictive policies regarding third-party data access. The data sharing practices affect not just privacy but also the security of user information, as each additional party with access represents a potential breach vector. Scores: Proton Pass 7/10, LastPass 4/10.
Controls You Can Actually Use
The availability and effectiveness of user-facing privacy controls determine how much agency individuals have over their own data. This includes settings for data collection opt-out, download and deletion capabilities, granular permission controls, and the ease with which users can exercise their rights under applicable privacy regulations. Proton Pass provides more comprehensive and accessible privacy controls. Scores: Proton Pass 8/10, LastPass 5/10.
How Clearly They Explain Themselves
At its core, transparency is about how clearly a service tells users what happens to their data. That means how understandable the privacy policy is, whether transparency reports exist, how promptly privacy inquiries are addressed, and whether changes to policy are flagged proactively. Proton Pass is the stronger performer on transparency overall. Without clear and accessible privacy communication, informed consent and trust are impossible. Scores: Proton Pass 9/10, LastPass 6/10.
Track Record Over Time
A service's history of privacy incidents, regulatory actions, and responses to vulnerabilities provides important context. Proton Pass has a stronger historical record on privacy, with fewer incidents and more responsible handling of the issues that have arisen. Past behavior is often the best predictor of future privacy practices. Scores: Proton Pass 10/10, LastPass 7/10.
The Final Verdict
When the full analysis is tallied, Proton Pass finishes at 54/60 and LastPass at 37/60. On privacy grounds, the overall winner is Proton Pass. Both products meet similar functional needs, yet the winner brings a more privacy-respecting approach to the dimensions that carry the most weight. Still, perfection is off the table for any service, so no matter which you choose you should actively set up its privacy options. Our advice is to round out your pick with additional privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, to assemble a thorough privacy posture. Should your threat model call for the strongest privacy possible, weigh whether an even more privacy-focused alternative exists in this category beyond the two compared here.
