โ˜…โ˜…โ˜…โ˜…โ˜… Recovery E-mail ยท Sep 17, 2024
I Love This! Open Source Authentication App (We know Any open source projects can be great for security and privacy and just by its name of being open source I don't know why we just instantly get a relief and can trust it with closed eyes) Anything which is made with open sourcing their codes shows how confident and caring they are with user's data protection and encryption protocols all just to keep us ACTUALLY SAFE! Then some bigger companies says it JUST TO SAY IT :) OPS Devs = Our FMLY.
