What is "SIWA"?

il y a 2 ansdiscuss

What are the other potential problems of the "email is authentication" pattern, under the following prescribed conditions? Maybe just these two?

(Prescribed Conditions)

- "Credential Recovery" complies with OWASP ASVS and is "adequately secure".

- "Credential Recovery" is the "weakest link" of authentication. (Other authentication methods require TOTP, etc.)

(Potential Problems)

- The financial cost of sending emails.

  - my guess is that, since I could not find of news of this issue,
    these users are only a small percentage (hopeful not yet)

- End-to-end response time for the "Credential Recovery" authentication process

  - my guess is that users who choose "Credential Recovery"
    authentication over other "happy-path" authentication are willing
    to wait, or are use to waiting.

(Non-problems)

- If the above conditions are specified, authentication security is not compromised.

(Terms)

- "Credential Recovery" as in OWASP ASVS V2.5 Credential Recovery, or "Self-service password reset" as in Wikipedia, or "forgot password" flow.

- "adequately secure" as in NIST SP 800-160 Vol. 1 Rev. 1, 3. System Security Concepts, 3.2. The Concept of an Adequately Secure System.
