Verification Code
A verification code is a type of security measure used to confirm the identity of users when accessing an online service or account. Verification codes are most commonly found in two-factor authentication (2FA). The purpose of 2FA is to ensure that only authorized users can gain access to sensitive information, accounts, and services.
In most cases, the user will be required to enter a one-time password (OTP) or other unique identifier in order to authenticate their identity before being allowed access. This OTP may come in the form of an SMS message sent directly to the user’s mobile phone number, or it could be generated by an authenticator app such as Google Authenticator.
The verification code ensures that no unauthorized person can gain entry into your account even if they have your username and password — because without entering the correct code they won’t be able to log in. It also helps prevent malicious actors from using automated tools like “brute force attacks” which try combinations of usernames and passwords until one works.
When you’re setting up 2FA for cryptocurrency websites and exchanges, you’ll usually need either a 6 digit numeric OTP delivered via text message; or you’ll scan a QR code with your smartphone camera then input what’s shown on screen into the website/exchange interface. Depending on which system is being used, there may also be some additional methods available such as email delivery for certain types of OTPs or biometric authentication via fingerprint scanners/face recognition etc..
For added security measures it’s always recommended that all users back up their recovery codes whenever possible so that you don’t lose access if something goes wrong with your device or network connection — this way you can still regain entry into your account even if there are any issues with receiving new codes at login time due to technical difficulties etc..
