Multi-factor authentication, often shortened to MFA, uses at least two different types of proof: something you know, something you have, or something you are. A password plus a code from an enrolled authenticator app is one common example. Two passwords do not count as two factors. A fingerprint or face check may unlock an authenticator; a biometric check by itself is not automatically an MFA login.
The reason MFA matters is simple: passwords get reused, guessed, stolen, phished, or exposed in unrelated breaches. If a password is the only gate, one stolen secret may be enough. MFA adds another step that makes account takeover harder.
Not every MFA method is equally strong. Properly implemented FIDO/WebAuthn security keys and passkeys provide phishing-resistant authentication; MFA also depends on how the authenticator is activated and verified. Manually entered one-time codes can still be phished. An authenticator app remains a useful improvement over password-only access, but it should not be described as phishing-resistant.
MFA works best when it is paired with good account hygiene. Administrators should use MFA first. Sensitive roles should not share accounts. Recovery methods should be protected. Teams should know how to report unexpected login prompts.
Account access protects the files, tasks, timelines, tables, documents, and decisions that live inside a workspace. MFA is therefore not an isolated IT feature; it helps protect everyday project and business work.
WorkStudio's current 2-step authentication uses an authenticator app and recovery codes. The security-key and passkey examples above explain general guidance; they are not a claim that WorkStudio offers those login methods.
