2FA
Two-factor authentication adds a second identity-verification factor beyond a password (such as a verification code or a hardware key) to confirm the intent of an operation and to improve account security.
Timeline (last 90 days)
One-time passwords (OTPs) are temporary codes generated by the time-based one-time password algorithm (TOTP), typically refreshed every 30 seconds, and used for two-factor authentication (2FA).
2FA typically requires the user to enter a dynamically generated one-time code within 30 seconds.
The APX browser tool provides a browser_handoff action for login, password, 2FA or CAPTCHA scenarios, recording a brief reason, marking the browser card as in handoff state, and waiting up to five minutes for the owner to complete the action.
The principle of least privilege includes: limiting token scope (read-only or restricted to a single repository), setting expiration times, preferring OAuth and app-specific passwords over master passwords, and keeping 2FA and payments in human hands.
Shared 2FA fundamentally weakens 2FA's protection of binding login credentials to a specific device or person
Team 2FA sharing tools typically follow two implementation paths: centralized key hosting and key distribution; the former facilitates instant permission revocation but makes the service provider a single point of risk, while the latter reduces server-side dependency but makes keys difficult to fully revoke.
Recommended user countermeasures include changing the Chess.com account password and ensuring it is not reused on other platforms, as well as enabling two-factor authentication (2FA).
Open-source maintainers should enforce two-factor authentication (2FA), prioritizing hardware keys or Passkeys over SMS verification.
NPM has announced plans to require human interactive 2FA confirmation before publishing by January 2027.
A 2FA login notification allowed the user to detect the abnormal login in time and quickly change critical passwords, preventing greater losses.

50%UnverifiedBy stealing session tokens, attackers can bypass two-factor authentication (2FA) and log directly into victims' accounts.
50%UnverifiedOnce a session token is hijacked, even if the account has 2FA enabled via SMS verification codes or hardware keys, it becomes useless, because authentication was already completed at the time the token was generated.
