Autentique's Professional plan looks attractive: R$ 99 per month with unlimited documents. Until you need biometric validation — then the credit system kicks in. 10 credits for R$ 10. 100 for R$ 49. 1,000 for R$ 390. And each selfie consumes one credit. For companies that validate dozens or hundreds of documents per month, the real cost quickly exceeds the advertised price.
On Signater, selfie with liveness detection is included in all plans. No credits, no add-on packages, no billing surprises. The price you see is the price you pay — from Starter to Enterprise. This predictability is what enables confident budget planning, without needing to estimate credit consumption or negotiate extra packages every month.
In Brazil's regulatory context, Law 14.063/2020 established three levels of electronic signatures — simple, advanced, and qualified — and consolidated the legal validity of digitally signed documents. This means the platform choice is not just a matter of convenience: it's a decision that affects the legal compliance of the entire operation. Signater supports all three modalities and operates in full compliance with current legislation.

Beware of "unlimited plans"
In recent months, hundreds of companies have migrated from platforms like Autentique to Signater. The most frequent reason: frustration with promises that don't deliver. Plans marketed as "unlimited" often hide per-feature charges, confusing interfaces that slow down operations, and support that doesn't resolve issues. The result is that teams end up avoiding the very tool they're paying for.
With Signater, everything is truly included — SMS, email, selfie with liveness detection, unlimited users, and self-service API. No credits, no per-send charges, no billing surprises. The price you see is the price you pay.
