Is public Wi-Fi safe to use for banking?

Concerns & risks

You use public Wi-Fi regularly and want to know whether it's safe.

Causes & evidence

The FTC explains that public Wi-Fi networks in places like coffee shops, airports and hotels are generally safe to use these days because most websites and apps use encryption, shown by https in the web address, to protect your information as it travels. The FTC still recommends some precautions: make sure you're connecting to the right network, since scammers can set up networks with names that look legitimate; keep your operating system, browser and apps up to date; use multi-factor authentication; and pay attention to browser warnings about a site's security. If a site shows a warning or isn't using encryption, avoid entering sensitive information.

Some sites and apps still don't encrypt every page. Your browser will typically warn you, and those warnings are worth respecting. Your phone's settings can help too. Many devices let you forget old networks, turn off automatic joining and show a warning before connecting to an open network. For work devices, follow your employer's rules, which may require a company VPN. When in doubt, use mobile data for banking and save public Wi-Fi for browsing and streaming.

Joining a network just because the name sounds official is the main remaining risk.

What to do

1. Confirm the exact network name with staff.
2. Check that sites show https before logging in.
3. Keep your device and apps updated.
4. Turn on multi-factor authentication for important accounts.
5. Turn off automatic connection to open networks.

Common mistakes:

• Joining look-alike networks
• Ignoring browser security warnings
• Running outdated software

ReportSpeedMan tip: Your phone's mobile data or hotspot is a simple alternative when you're unsure about a network.

What I would actually do

I'd confirm the network name with staff, check for https and keep MFA on my bank and email.

The trade-off people miss: worrying about the Wi-Fi itself can distract from bigger risks, such as reused passwords and skipped updates.

Signs it worked

You connect only to confirmed networks and every login uses https and MFA.
