That team member has an existing Square account tied to that email, so when she goes to accept the invite, it's asking her to login into the existing Square account for that email.
If she doesn't know the password, she can use the forgot password flow. The issue she's probably running into when she does that from the email invite is the email is "masked" (probably looks like r***@acme.com). This is a security thing, but it's messing with the forgot password flow. So she should just type her full email address in, and she'll get the forgot password email.
Sorry this is a bit confusing. I've passed along to the team to see if we can fix the issue with the masking. This is sort of specific to team members that have an existing Square account and are trying to login, and then need to reset password, but definitely confusing if you're in that case.
