I got a message that my connection is not secure

If you get a message in your browser concerning an non-secure connection or an incorrect security certificate:

• Make sure that the correct address is entered in your browser's address bar — mail.yandex.com or passport.yandex.com, and that the / symbol is after com rather than a period or some other symbol.
• Make sure that your date and time are correctly set on your computer. If the wrong date or time is set, then the system may incorrectly determine that the certificate period hasn't started yet or that it's already expired.
• Make sure that your antivirus settings are not configured to check HTTPS-connections.
