Ever been greeted by a popup saying, The certificate doesnt come from a trusted authority?
when trying to access a website?
When your Android detects a security certificate, it downloads it to your gear.
If you’re gonna wanna delete these stored certificates, it’s possible for you to.
But first, lets address what use Android certificates are to everyday Android users.
Once a developer is done making an app, they need to sign the apps credentials before uploading it.
If it is not, users are advised against installing the app or logging into the internet.
Android Security Credentials
Now more than ever, privacy is a concern when accessing the web.
Android OS certificates use public key infrastructure to encrypt data on both ends.
They are used over exchange servers, private networks, and Wi-Fi to access secure data from a gear.
Some applications, like Access or Microsoft Exchange, download the credentials themselves.
You would usually remove a certificate if you no longer trust a source.
Removing all credentials will delete both the certificate you installed and those added by your equipment.
Depending on your gear and Android software version, these steps may vary slightly.
Conclusion
It just goes to show you that even technology has its trust issues.
If an app gives you reason not to trust it, delete that certificate.
