SD Card Access?

If someone has taken my camera and the SD card inside it, can they see what’s on the SD card without my acct username and password? Like if they take out the SD card and try to read it some other way, will it be readable and they’ll be able to see whatever videos are stored on it?

I have the Netvue Birdfy camera and I took the SD card to my PC and moved all the videos to a folder. I was able to open the files and watch the videos without any passwords.

It won’t read my sad card it did for like 2 months then quit y

Sorry for the inconvenience brought.
