A 45kk takes account security seriously. Every login session is protected by TLS encryption — all data travels encrypted between your device and the platform's servers, making interception impossible.
Beyond standard encryption, you can enable two-factor authentication (2FA) in your account settings — an extra layer of protection that requires a temporary code in addition to your password, even if someone gets hold of your credentials. We strongly recommend enabling 2FA for all 45kk users.
Never share your password
45kk will never ask for your password by email, chat, SMS, or phone. If anyone claims to be from 45kk support and asks for your password, it's a fraud attempt. Report it immediately via live chat.
All communication between your device and 45kk is encrypted with TLS. This includes your password on login, Pix deposit data, and any other information transmitted while using the platform.
Enable 2FA in your 45kk account settings to add a second layer of security. At every login, in addition to your password, you'll enter a one-time code generated by an authenticator app on your phone.
45kk never stores your password in plain text. The system saves only an irreversible cryptographic hash — not even platform staff can see your password. Only you know it.
45kk sends email notifications when a login is detected from an unrecognized device or location. If you receive an access alert you don't recognize, change your password immediately and contact support.
Forgot your password? 45kk's recovery process uses email verification with a one-time temporary link. The link expires in 30 minutes — if it runs out, just request a new one with no hassle.

Sometimes old cookies or cached data can cause login issues. Try accessing 45kk in a private/incognito tab or a different browser — Chrome, Firefox, Safari, or Edge. On mobile, try using a browser app instead of your device's default browser.
After multiple failed login attempts, 45kk temporarily blocks access as a security measure. Wait 30 minutes before trying again, or use the password recovery process to reset your password and regain access immediately.
