Houston, we have an OTP problem

Hi folks. Once upon a time I had a Xiaomi phone and an app (2OTP) which worked like a charm - filled password, then 2OTP and I received immediately the OTP (just numbers). Now, after I changed my phone, everything has changed, and frankly I am totally lost in a dark forest were 2+2=5....:) When I open 2OTP or ANY other two factors auth. app, I don't receive any number, but a lot of messages....tasking me to take a shot of a QR code (what code??) and a lot of exoteric stuff. I am here, because I use also prettier lichess on Chrome, (my access is immediate, without password request), but I do want to go back to lichess.org on Safari.
Any advice?
Thanks!

MacBook Air, Catalina last version - Samsung Ph, Android.

So just to clarify, because it is not very clear from your post:
- Did you have the multiple devices option enabled when you used the 2fa on your previous phone?
- If no, did you install any 2fa app on your new phone or on your Mac?
- If yes, did you connect lichess to the app?
- If no, did you go to lichess.org/account/twofactor and followed instructions?

Thanks for your reply
- I think I had the multiple devices enabled when I used my previous ph, cause I never had troubles when authenticating.
- When I bought my new ph, I transferred every app from Xiaomi to Samsung, and of course I transferred 2OTP too.
- I think I have not connected 2OTP to lichess. Maybe this is the problem.
- If I go to the link you sent me, I need an authentication code...which actually I can't get :(

Btw, could you please suggest me a good and simple authentication app for Android?
Thks again!

You don't get the code because you probably aren't connected with lichess yet.

I can suggest Authy, here's a guide to getting started with it: support.authy.com/hc/en-us/articles/115001943608-Welcome-to-Authy-. Follow the instructions there and in the following articles.

Thanks. Now I've Authy on my Samsung. When I open it
1. I see Twitch token
2. I go to Add Account
3. I see: Scan the QR Code on the website where you are enabling 2FA / No QR Code? Enter code manually.

This is the point: where can I see my lichess code?
THKS!

My password
An OTP

yes if you get your otp then you can change password if you forgot it
also just install the same otp app you used and login in the otp should be there
