Are these security certificates legit Samsung A34?

[askingquestion]

(Big bulk of images next, sorry) Hi, for context I made another post explaining my situation here. 

After checking the advice given I could only find 'FindMyMobile' in user certificates. Now I checked the security certificates and they look something like this: (I have a Samsung A34)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If someone could ease my doubts and confirm if those certificates are ok or if they are fake I would appreciate it. I'm not very skillfull technology so I need some guidance as to what can I do or what that means for my security online. Thank you very much! 🙂

Mine are almost the same and, like you, I wanted to know if they were legit so I looked up each one and they all checked out. I also deactivated the ones that were expired. You might have some as well so just look at each one and see their exp date.

Hello again! User Certificates, from my understanding, are installed by system apps you use, or indirectly, like with VPNs. As for Security Certificates, they are installed by the device manufacturer (in this case, it's Samsung). These certificates represent "trust", and are signed by different authorities. Your device presents these different certificates to your browser. I can only guarantee the legitimacy of Amazon, Comodo, DigiCert, GoDaddy, and Google. These companies are known for selling SSL certificates. The websites they sell these certificates to show this to the browser and trusts them if they have the same certificate(s) stored on-device.

Thank you so much. Sorry for being so dense but as I don't have that much knowledge I resort to you: Do you think it would be a good idea to see the expiration date of these one by one and disable those that have already expired? (As recommended by another comment) Or do I just leave them as they are?

Also is it normal to have Turkish, Swedish, Chinese, French etc. security certificates?

Thank you so much for your patience and understanding. ♡

Based on my own certificates, most, if not all the certificates should still be valid. If not, you can choose to follow the coment above, but it'll be tedious. Also, it should be normal for different certificates to be there since, well, the internet is spread around the world. Websites and certificates can be based in other countries. And it's not a problem 👌.
