Email Security Tips for Michigan Customers

Email is a key part of daily life, but it’s also a common entry point for cybercriminals. At Commercial Bank, we’re committed to helping our customers in Alma, Grand Rapids, Greenville, Hastings, Ithaca, Mason, Middleton, St. Louis, and Okemos stay safe online.

Here are practical tips to help you protect your email account and personal information.

Use strong and unique passwords

Create a password that’s hard to guess by using a mix of uppercase and lowercase letters, numbers, and special characters. Avoid using the same password across multiple accounts. Using a password manager can help you generate and store secure passwords safely.

Turn on multi-factor authentication

Multi-Factor authentication (MFA) adds an extra layer of security. It requires a second step to verify your identity, such as entering a code sent to your phone. Even if someone has your password, MFA can block unauthorized access.

Be careful with links and attachments

Phishing emails often include links or attachments that can infect your device or steal information. Always double-check the sender’s email address and be cautious with unexpected messages, even if they appear to come from someone you know.

Look out for fake or spoofed emails

Cybercriminals often disguise emails to look like they’re from trusted sources, including banks. If an email asks for sensitive information or urges immediate action, don’t click anything. Instead, contact the business directly using their official website or phone number.

Avoid checking email on public Wi-Fi

Public Wi-Fi networks can be unsecured, which makes it easier for hackers to intercept your information. Avoid accessing email or financial accounts in public places unless you’re using a trusted VPN connection.

Keep your devices and apps updated

Software updates often include important security patches. Keeping your operating system, email app, and antivirus software up to date can protect you from known vulnerabilities.

Know what to do if your email is hacked

If your account is compromised, act quickly. Change your password, enable two-factor authentication, and check your account settings for unauthorized changes. Warn your contacts not to open suspicious emails from your address. View the full guide on what to do >
