A "no account found" message usually means one of two things: the account was never created, or it was created with a different login method.
If you have not created an account yet, sign up here: https://venice.ai/sign-up
If you already have an account, it may have been created with a social login such as Google, Apple, or another provider, so try those options on the sign-in page: https://venice.ai/sign-in
If you set a password on the account, you can sign in with your email and password directly.
An email verification code is only sent when you do not have a password set, or when you sign in on a new device for the first time.
