Company profile

researched Sep 2026

HiddenLogin is a Detroit, Michigan-based privacy software company that operates an online alias manager. Its stated mission is to protect users' online identities by generating a unique alias for every website a person visits, so that sites cannot access, link, or resell their real personal data.

The product set centers on email masks, phone/SMS aliases, and generated identities that stand in for a user's real identifiers during sign-up and other online interactions. The company is classified as a data-privacy technology provider selling recurring SaaS to consumers, with global geographic exposure.

Business model

HiddenLogin sells privacy software directly to consumers on a recurring, subscription-style SaaS basis, combining a free tier with a paid plan.

Recurring subscription revenue from a paid consumer plan alongside a free tier.

▸Full profile — market position, technology, go-to-market, geography, history

Market position

A pre-seed, privately held company in the consumer data-privacy software category, positioned alongside other online identity-masking and alias services such as Phantom LogIn, Mask.it, Invisit, and Cloaked.

The approach is built around issuing a distinct alias per website rather than a single shared identity, so that personal identifiers are never exposed to the sites a user interacts with and cannot be correlated across them.

Technology

Alias-generation technology that creates per-site identities, email masks, and phone aliases used in place of a user's real contact details.

Go-to-market

Individual consumers seeking greater privacy and security in their online interactions.

Geography

Headquartered in Detroit, Michigan, United States, with global geographic exposure.

History

The company was founded in 2020 and is headquartered in Detroit, Michigan. It took part in the Techstars Chicago accelerator in 2021 and is classified as a pre-seed, privately held company with roughly six employees as of early 2024.
