I visited a legitimate website and entered my login details while it was using HTTPS. Shortly afterward, Safari displayed a "connection not secure" warning, and I noticed my Wi‑Fi connection had dropped around the same time. I've seen the same warning before when opening or refreshing a page during a Wi‑Fi outage, even though the website normally uses HTTPS. Does this put my login credentials at risk, or is Safari just showing a fallback error page because the connection was interrupted?

“Connection Not Secure” usually means the page currently being displayed was loaded over plain HTTP rather than encrypted HTTPS. If the site normally uses HTTPS, a brief network interruption can cause Safari to show an error or fallback page while it tries to reconnect. That warning by itself does not prove your login details were exposed, but you should avoid entering credentials unless the address bar clearly shows HTTPS and the correct domain. Banking and other sensitive sites should always use HTTPS.
If you had already submitted the login form before Wi‑Fi failed, the request may simply have been interrupted. Check the address carefully when reconnecting and sign in again only after the secure HTTPS page loads. For extra caution, change the password if you noticed the warning while actively submitting it, especially if the site’s address changed or looked unfamiliar.
Testing with airplane mode can produce a similar warning because Safari is trying to load a page without a working network connection. That behavior alone doesn’t indicate that the site suddenly became insecure.
