1Password and LastPass's security models are different.

LastPass accounts are protected by an account password. 1Password accounts, meanwhile, are secured with two powerful layers of protection: a password – which we never store and only you know – and a Secret Key. Your Secret Key is 34 letters and numbers, separated by dashes. It’s stored on devices you’ve used to sign in to your account, and in your Emergency Kit. Only you have access to it.

This dual-layer encryption keeps your saved credentials and other sensitive information safe. Even a breach of 1Password's systems would pose no threat to your vault data.

We’re regularly assessed by independent experts to make sure our security approach is rock solid.

LastPass has experienced multiple data breaches in the past, making it unreliable and unsafe. 1Password continues to be a reliable password manager with an uncompromising commitment to security.

1Password's security model is designed to protect your data even in the unlikely event of a breach. That's because each user's vault data is protected by a password – which we never store and only you know – and a Secret Key that's mathematically infeasible to crack.

LastPass has been breached before, resulting in compromised customer data. The company has taken positive security actions as part of ongoing containment and recovery efforts. However, do you want to use a password manager with that history of data breaches?

With 1Password, you can have peace of mind knowing our approach to security which combines zero-knowledge architecture and end-to-end encryption is designed to give your data the best possible protection.

LastPass provides fewer SIEM integration options, which can limit the visibility and control required by security operations teams.

If your organization values tools that can integrate deeply with other security infrastructure, 1Password stands out. Its extensive SIEM compatibility helps you build a consolidated view into security events across your organization.

1Password holds more ISO certifications than LastPass, including ISO 27001, 27017, 27018, and 27701. 1Password is also SOC 2 Type 2 compliant.

LastPass, by contrast, lacks this broad certification scope, which may lead to gaps in compliance assurance for organizations prioritizing stringent data protection standards.
