I haven't used runemate in about 2 months and I came back today to log in and found my account needs the authenticator code, i dont have the code anymore because i have a new phone now so what can i do? I have a bit of money on my account and dont really want to lose it

Since you lost all access...

What if I lose my phone/authentication method?
You should have kept your back up codes to help you in a situation like this. If you didn't, unfortunately there isn't anything we can do to reset your account.
