HashiCorp has expanded multi-factor authentication (MFA) support across its open source and all HashiCorp Cloud Platform (HCP) Vault tiers, previously available only through Vault Enterprise. This release adds login MFA support for Vault OSS and HCP Vault, enhancing zero trust security best practices for all users. The new integration offers an additional authentication step using time-based one-time password (TOTP), Okta, Duo, or PingIdentity. As sophisticated attacks from hackers and ransomware increase each year, organizations need modern, automated security solutions that rely heavily on identity to protect critical infrastructure. Adding MFA to Vault open source and HCP Vault makes identity-based security for both humans and machines consistent and accessible at all levels of infrastructure.
