Features of authorization on Instagram
When logging in from a new device, unstable connection, VPN, proxy, or low-reputation IP, the system may sometimes display an “invalid username or password” error, even if the data is entered correctly.
This does not mean that the username or password is incorrect. In most cases, the error is related to Instagram's security checks and login conditions.
100% cookie authentication guarantee.
Recommendations:
— Use a stable internet connection
— Log in through the official application or browser
— Avoid public VPNs, proxies and suspicious IPs
— If an error occurs, try a different connection, device, or sign in again later
— If the login from another connection is successful, the account data is considered correct
Important:
This error is a feature of Instagram's security system and does not always indicate a problem with your account or incorrect login information.
