Niconico 2FA: How to Set Up an Authenticator App
Niconico lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your Niconico account safe even if your password leaks.
A Niconico account is linked to your profile and payment details, so 2FA is worth it. Besides an authenticator app, Niconico also offers email codes. An authenticator app (TOTP) is usually the best balance of security and convenience.

Save a way to recover your account.
If Niconico shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Niconico recovers accounts (support, an admin, or another sign-in method) before you need it.
Menu names on Niconico can change — the official Niconico 2FA documentation ↗ always has the exact, current path.
How to recover your Niconico account
If you lose access to your authenticator and Niconico gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Niconico doesn't, or you didn't save them, use Niconico's account-recovery or support process (or ask your admin, for a work account) to get back in.
