If you find something suspicious like spelling mistakes or others on the web page you are on, check the certificate by clicking on the padlock on the left side of the address bar. Check for which organization it is issued. If it is not issued for the company name on the site, it is highly recommended that you close it and access the site from search engines or a bookmark. Change the password of the email address associated with the account as well as the account password.
