Raivo - Secret/Seed - Settings

[Chrom3-Gl4ss]

Hi, I’ve done much research and so far, I think Raivo is one of the BEST or actually even the best app for otp.

I just have a few questions regarding this app.

What are the best settings for encryption? To my knowledge in the App there’s “SHA1, SHA256 and SHA512”

I’m sure SHA-512 is the best one right?

But how do I find out what token to use? 6,7 or 8 digits?

And how on earth do I find the Secret/Seed, I know it says to get QR code, but what one? Like for example setting up code for example, Facebook, do I then need a special Facebook QR to generate a specific seed for that particular site? Or do I need to generate this seed by making my own? Then use that seed to all of my otp? (Which I don’t know how to do and not sure if that’s the best approach to keep things secure?)

I need help! Haha 😆

Thanks. Great app btw. Great work 👍
