What is One-Time Password (OTP) and 2-Step Verification

2-Step Verification (aka: two-factor authentication) requires a one-time password or other second step after you entered your password. It adds an extra layer of security to your account in case your password is stolen.

A one-time password (OTP) is an automatically generated numeric or alphanumeric string of characters from the site with 2-step verification enabled that authenticates a user for a single transaction or login session. An OTP is more secure than a static password, especially a user-created password, which may be weak and/or reused across multiple accounts.
