1Password vs Kaspersky

1Password vs. Kaspersky

Managing sensitive login information, financial details, and private files across multiple devices requires a password management tool that combines strong encryption with dependable syncing and accessibility. 1Password and Kaspersky Password Manager each offer encrypted vaults, cross-platform compatibility, autofill, and password generation features. The comparison below reviews their features, security structures, and pricing models to help clarify how they differ and where each one fits best.

Service range

1Password provides encrypted storage for passwords, credit card information, secure notes, documents, and identities. They support Windows, macOS, Linux, Android, iOS, and major desktop browsers through browser extensions. The service includes password generation, autofill functionality, encrypted sharing between authorized users, and synchronization of vault data between devices. Users can create multiple vaults that separate work, personal, or shared account data. 1Password is available to individuals, families, and businesses, and all offerings share the same encryption structure, with administrative controls available where required for organizational accounts.

Kaspersky Password Manager provides encrypted storage for passwords, bank card details, documents, secure notes, and images. They support Windows, macOS, Android, and iOS, with synchronization across devices carried out under encryption. Their service includes autofill functionality, password generation, and vault access from supported devices. Kaspersky applies the same vault structure for all users regardless of whether they are on the free or paid plan, with the only distinction being the storage limit. The interface supports the encrypted organization of stored items and synchronization within their zero-knowledge model.

Security and compliance

1Password applies end-to-end encryption and a dual-key model. Decryption requires both the master password and a locally generated Secret Key. The Secret Key is never transmitted to 1Password’s servers and remains local to the user's device. Because neither the master password nor the Secret Key is shared externally, vault content cannot be accessed by 1Password or other parties. Vault contents stay encrypted during syncing, and the encryption model applies consistently to individual, family, and business accounts.

Kaspersky Password Manager uses AES-256 encryption and enforces a zero-knowledge structure. Vault data, including passwords, documents, banking details, and images, stays encrypted locally and during synchronization. Kaspersky does not store or recover the master password; therefore, encrypted vault content remains inaccessible to the provider. If a user loses their master password, their vault cannot be restored. All stored items receive the same encryption treatment, and the encryption model is uniform across the free and paid versions of the product.

Pricing

1Password offers tiered subscription plans. The Individual plan costs $2.99 per month when billed annually. The Family plan, which supports up to five users, is priced at $4.99 per month when billed annually. Business plans are available at $7.99 per user per month with annual billing. All tiers include the same encryption structure, with administrative tools added for business accounts. 1Password does not provide a permanent free version; instead, a free trial period is available before billing begins.

Kaspersky Password Manager follows a freemium model. The free version limits the number of stored entries. Upgrading to the paid version allows unlimited storage and full synchronization across supported devices, priced at $14.99 per year. The encryption model remains the same for both tiers, with the only difference being the removal of storage limitations in the paid plan.

Conclusion

Both services encrypt stored data and prevent provider access through zero-knowledge approaches, and both support major operating systems and syncing across devices. 1Password provides multi-vault organization, encrypted sharing, and subscription tiers for individual, family, and business use, while Kaspersky delivers AES-256 vault protection, cross-device syncing, and a free-to-paid path based on storage limits, making the final choice dependent on whether a subscription-based multi-vault structure or a simpler freemium model better aligns with user needs.
