Sign documents securely
SignPoint360 is the signing page for documents sent to you by MStack360. Read the document, sign it in your browser, and you are done — no account, no app, no password.
You need the link from your email
Every document has its own private link, sent to the address the sender chose. Open that email and press Review and sign.
Links are single-use and expire, so an old one will not open a document. If yours has stopped working, ask the sender to send a new one.
Why this page exists. Documents sent for signature stay under MStack360's control on infrastructure it owns — not a third-party signing service. This page holds no account for you, sets no tracking, and runs no JavaScript at all.
