GS5 got stolen with an added SD card that stored my password filled memo, can the thief access it?

[AC Question]

My Samsung Galaxy S5 was stolen with an sd card I had added to expand memory. The SD card probably has my memo (notes) app on it which I used to list all of my passwords for everything on. Will all of this be accessible to the thief? Can I somehow factory reset the device from afar even though I know that it is turned off? If it factory resets will the added SD card also lose it´s memory like I want it to?

Welcome to Android Central! If the SD card or that file aren't encrypted, then yes, someone could potentially access it. You could always use Android Device Manager to send a remote wipe command, so when that phone is turned on and connected to the web, it should receive the command, but this won't wipe the SD card. To be safe, I'd change all of those passwords now.
