The standalone, open-source toolkit, currently in early alpha, is designed for developers exploring secure access patterns rather than production use. The SDK establishes a framework for just-in-time credential access with human oversight. When an agent needs credentials, requests are sent through an end-to-end encrypted channel for user approval, ensuring agents operate within tightly scoped boundaries rather than having persistent vault access. The framework provides just-in-time credential access, end-to-end encryption, human-in-the-loop approval and prevents plaintext credential exposure. The SDK is available as an open-source project for community collaboration and experimentation, though business production use is not yet recommended.
Bitwarden has announced an enterprise policy that extends single sign-on convenience to web-based applications lacking native SSO support. The feature enables administrators to designate approved applications for automatic login through the Bitwarden Admin Console. Once configured, employees can launch and log into approved applications from identity provider dashboards like Okta or Microsoft Entra ID with a single click. Bitwarden automatically fills and submits stored credentials from encrypted vaults, creating a consistent login experience. According to 451 Research, only 34–66% of enterprise applications use SSO at 56% of companies, leaving many credentials unmanaged. The new policy addresses this gap by bringing SSO-like convenience to both managed and unmanaged applications whilst maintaining administrative control over enabled URLs. The feature is available now for Bitwarden Enterprise plan users.
Bleeping computer: Bitwarden adds support for passkey login on Windows 11. March 10, 2026 Bitwarden announced support for logging into Windows 11 devices using passkeys stored in the manager's vault, enabling phishing-resistant authentication. The new feature is available for all plans, including the free tier, and allows logging into Windows by selecting the security key option and scanning a QR code with a mobile device to confirm access to the passkey stored in the Bitwarden encrypted vault. Bitwarden is an open-source password and secrets manager that can store account passwords, passkeys, API keys, credit card details, identity data, and private notes.

Bitwarden has announced support for logging into Windows 11 using passkeys stored in its vault, enabling phishing-resistant authentication directly to the operating system. The capability allows users to authenticate with cryptographic credentials rather than passwords, without transmitting shared secrets. In supported configurations, Windows login presents a QR code that can be scanned with a mobile device to confirm access to a passkey stored in the Bitwarden vault. The integration works with Microsoft Entra ID environments and builds on native passkey integration in Windows 11. Founded in 2016, Bitwarden serves over 50,000 businesses and 10 million users worldwide. The company offers password, passkey and secrets management solutions based on open source security standards.
Bitwarden introduces 'Cupid Vault' for secure password sharing. * February 12, 2026 * 04:55 PM * 0 Bitwarden has launched a new system called 'Cupid Vault' that allows users to safely share passwords with trusted email addresses. Cupid Vault works by allowing users of the free version of Bitwarden to create a 2-person shared vault called an 'Organization'. Other users can access the logins inside the Organization space with credentials assigned by the owner of the account. Inviting a user (partner, friend, family member) to an Organization can be done by adding their email address as a second member. This way, Bitwarden users can share in a secure way collections of login pairs for media streaming service accounts or other online platforms. Setting up an Organization and creating shared collections is possible by logging into the Bitwarden vault via the web interface. To prevent adversary-in-the-middle enrollment attacks, vault owners can verify through a fingerprint phrase that the intended member is getting access. The shared vault is completely isolated from the personal vault. Access to the Organization vault and the secrets it contains can be revoked at any time, and sharing can be configured in both directions. Bitwarden published a detailed guide on how to set up and use Cupid Vault, which explains that ownership of items within a new Organization isn't tied to their creator, as both members can perform editing or deletion actions. Bitwarden is a popular open-source password manager that lets users securely store, generate, and autofill passwords and other sensitive information. It's cross-platform, supporting a range of browsers, desktop operating systems, and mobile platforms, and protects stored data using end-to-end encryption. The new Cupid Vault feature, launched ahead of Valentine's Day, is available at no charge to all users and can be set up through the free plan. However, there's a limit of 2 Collections and 2 users each. Family, Teams, and Enterprise plan users already get multiple users, collections, and granular role-based access control permissions, so Cupid Vault is redundant for paying tiers and shouldn't be confused with the secret-sharing features available to them. Modern IT infrastructure moves faster than manual workflows can handle. In this new Tines guide, learn how your team can reduce hidden manual delays, improve reliability through automated response, and build and scale intelligent workflows on top of tools you already use.
