Reusing the same passwords is a common practice because it's easier to remember. But when one login is exposed, it puts multiple accounts at risk. Nowadays, phishing attacks trick users into giving up credentials every day. Credential leaks and data breaches happen often, leaving business and personal data vulnerable. As a result, many people rely on built-in browser password managers for convenience, despite their limited advanced security, cross-platform control, and recovery options.

To address these limitations dedicated password managers like Proton Pass and LastPass come into place. Proton Pass emphasizes privacy with open-source code and Swiss data protection. LastPass delivers password management for both individuals and businesses, with strong collaboration tools.

This comparison guide covers how each platform works, how it differs in security, and trust models. It also provides a detailed overview of their pricing so you can make an informed decision.

Proton Pass Vs LastPass: Key Features Comparison

Password Storage And Autofill

Proton Pass uses an end-to-end encryption model that protects passkeys, credit cards, and passwords. It stores all passwords and enables instant sign-in through autofills across devices. Users can create unlimited logins and store them in encrypted vaults.

LastPass stores all the passwords and essential information in a password vault and autofills the credentials when the user logs in. It allows users to generate unique passwords for new and existing accounts and syncs them across all the trusted devices. The tool's autofill feature works for payment information and addresses to streamline the online checkout process.

Winner: This ends in a tie between both platforms as both offer comparable autofill and password storage capabilities. Both provide unlimited password storage, automatic sync across devices, and seamless autofill functionality.

Two-Factor Authentication (2FA)

Proton Pass offers an integrated Two-Factor Authentication (2FA), which provides an additional layer of security for the account. It generates six-digit Time-Based One-Time Passwords (TOTPs), making it easy to sign into online accounts.

The platform does not require approval from a third-party authentication app; instead, it creates secure TOTP codes for websites with saved login details. The 2FA feature copies codes automatically to the device clipboard on Android and displays notifications with codes on iOS. Furthermore, users can scan QR codes or manually enter 2FA keys to configure authentication.

On the other hand, LastPass supports 6-digit generated passcodes, SMS, and push notifications for one-tap login. The platform partners with Duo Security to bring two-factor authentication to vault logins. This partnership supports multi-user deployment and provisioning for added admin control. Moreover, the tool offers biometric authentication, including fingerprint scan and voice recognition.

Winner: Proton Pass takes the lead due to its 2FA authentication within the password manager. Its automatic code copying and TOTP codes provide a more streamlined experience.

Cross-Platform Availability

Proton Pass offers cross-platform support across various devices. This includes Windows, macOS, iOS, Android, and Linux platforms. It also provides browser extensions for Chrome, Edge, Brave, and Firefox. Users can securely access passwords and sync data across all other supported platforms.

LastPass allows users to sync the password vault with unlimited devices across desktops to smartphones, and tablets. The platform supports iOS devices, including iPad, iPhone, and Apple MacBook, and Android devices. Additionally, it supports Windows OS computers, laptops, and tablets. With automatic device sync, items saved to the password vault are automatically synced across all LastPass-connected devices.

Winner: Proton Pass comes out ahead because it allows free users to sync across all devices without any restrictions.

Security Dashboard

Proton Pass offers a Pass Monitor that enhances online security by identifying vulnerable accounts and receiving alerts regarding data breaches. The platform works by identifying weak or reused passwords and gives notifications of 2FA to improve online security. The dark web monitoring services give immediate alerts if personal information is compromised by a data leak, whereas the Proton Sentinel prevents hackers from gaining access to the accounts.

LastPass offers a digital security dashboard that accesses password security and monitors accounts for data breaches. The dashboard allows users to update reused and weak passwords, along with recommendations to update them through the password generator tool. It also assesses the security score and monitors email addresses for involvement in data breaches. By enabling dark web monitoring in the security dashboard, LastPass monitors account security and gives alerts via email and in-product.

Winner: LastPass leads in its comprehensive security dashboard that provides numerical security scores and automatic updates. Its centralized dashboard with scoring helps users understand the account's security.

Email Aliases And Identity Protection

Proton Pass automatically creates unique email aliases when users sign up for new online accounts to safeguard the corporate email addresses. Aliases randomly create email addresses that users can use when signing up for accounts. Users can easily deactivate aliases to stop receiving unwanted emails while keeping their real identity private. This protects the privacy of the user’s account and prevents phishing attacks.

On the other hand, LastPass does not offer a native email alias. Instead, the platform focuses on generating username and passwords. It generates unique usernames to protect identity online and relies on third-party email providers for email aliasing.

Winner: Proton Pass dominates this category with its hide-my-email alias feature that LastPass completely lacks. Its generation of unlimited email addresses directly within the password manager provides significant privacy advantages and spam protection.

Password Sharing

Proton Pass offers a secure and easy way to share passwords with family, friends, and colleagues. Users can share a single item or share an entire vault with specified recipients. Besides sharing passwords, the platform also shares sensitive information, such as credit cards, notes, and hide-my-email aliases. Moreover, the tools generate secure links for sharing with users from any device and all major operating systems.

LastPass offers the password sharing functionality for both personal and business use. In personal password sharing, the platform ensures security through its zero-knowledge model that keeps the plain-text sensitive information accessible only to users. It easily controls access by hiding plain text passwords from users, and provides temporary access to shared passwords like Wi-Fi, Google Home, and streaming login credentials. Business password sharing provides group-based sharing that streamlines collaboration among teams and enhances cybersecurity. It protects information from hackers through Advanced Encryption Standard (AES)-256 encrypted password sharing.

Winner: LastPass takes this category with its comprehensive sharing capabilities for both personal and business users. Its restricted folder access, admin controls, activity tracking, and password visibility options make it ideal for team collaboration and enterprise use cases.
