Server lost users logins

Hi to all
I am using the latest version of traccar for Arm pcs.
I have installed it in one orange pi zero board and for the moment I am testing it.

Until know every time I was powering off my board I had no problem with my testing users login information or with my customize admin user settings.

Today I decide to shutdown my pc board in order to remove my SD card with the armbian os / traccar server in order to copy some files to my Main pc (Ubuntu distro)

After that when I placed again the SD card to my Orange pi zero and powered on... When I try to login with my users or with my customized admin I was getting error that I was placing wrong login informations

I tried to login as admin but with the original settings (user and password) and worked.

It is like the server was reset..

Any explanation?
Can I find somewhere my previous setup to load it again?

Thanks In advance

It's a common issue of raspberry pi with SD card. Configure it to use flash drive instead of SD card.

Thanks for the info.
I checked my Armbian distort and has a tool to make my eMMC setup to install it and boot from USB drive.

So I will proceed with that.

Thanks again for the help
