Two ways to use OneTimeLogin
Whether you are tired of making accounts or tired of building sign-in, you are in the right place.
For people
One account. Every partner site.
- Sign in once and stay signed in across every connected site.
- No separate password per site, and nothing to reset.
- See every site you have connected, and disconnect any of them.
- Update your details in one place instead of a dozen.
Already have one? Log in
You are signed in as your account.
For businesses
Sign-in you never have to build.
- Drop in SSO instead of writing and maintaining auth code.
- Visitors from other partner sites arrive already registered.
- Roles, permissions and audit logs from an admin dashboard.
- Conversion and drop-off analytics for every sign-in.
