Turvakoodimistin

Turvakoodimistin is a Finnish term that translates to "security code generator" or "security token" in English. It refers to a device or software used to generate temporary, one-time passwords (OTPs) or codes that are used as a second factor in multi-factor authentication (MFA). These codes are crucial for enhancing security by ensuring that even if a username and password are compromised, unauthorized access is prevented without the second factor.

Turvakoodimistin can take various forms. Hardware tokens are small physical devices, often resembling key fobs, that display a constantly changing code. Software tokens, on the other hand, are applications installed on a smartphone or computer that generate these codes. The generated codes are typically time-based (TOTP) or event-based (HOTP), meaning they change at set intervals or after a specific event, respectively.

The primary purpose of a turvakoodimistin is to verify the identity of a user attempting to access a system or service. When a user logs in, after entering their primary credentials, they are prompted to enter the current code displayed by their turvakoodimistin. This code is synchronized with the authentication server, and if it matches, the login is considered successful. This significantly reduces the risk of account takeovers due to phishing or password breaches. Many Finnish banks and online services utilize turvakoodimistin technology to protect their customers' accounts.
