Most login issues arise when users attempt to link their logins to multiple products. If you are trying to link your logins to OmegaOne, OmegaRecruit and/or myOmegaFi:
REGISTER your login to the first product.
If linking OmegaOne to another product, we always recommend you establish your OmegaOne login FIRST and then link your other accounts. See: Creating New OmegaOne Login
