You can join the SI Passport network without a wallet. A Guest Passport is made with a passkey (Face ID, a fingerprint or a security key), collects the stamps of every SI site you visit and follows other Passports. Attach a wallet any time with a free message signature, and it becomes a full SI Passport with its stamps.

Tap Join without a wallet and confirm with Face ID, a fingerprint or a security key. Your Guest Passport number is yours.
Sign in on sicto.si, thesimind.si, siscto.si, enterrsi.si, tsio.si and codeflex.si. Each site adds its stamp, once.
Follow the SI accounts and any Passport by its handle, from your Passport on any SI site.
Tap Attach a wallet and sign one free message. Your Guest Passport becomes a full SI Passport, and your stamps and follows come with you.
A passkey is a key your phone, computer or security key keeps. sicto.si only ever sees its public half, so there is no password to steal.
In browsers that support related origins, the same passkey works on all six SI sites. Elsewhere it works on the site where you made it.
Every join and sign-in is checked on sicto.si: the challenge, the site, the signature and the counter of your passkey.
A few Guest Passports a day per connection and per browser, so the numbers and stamps stay real.
A Guest Passport is an SI Passport made with a passkey instead of a Solana wallet. It has its own number range written with a G, shows Guest where a tier would be, collects the network stamps of the six SI sites (sicto.si, thesimind.si, siscto.si, enterrsi.si, tsio.si and codeflex.si) and can follow Passports. It cannot vote, earn checks, tiers or rewards, and never counts as a holder. Attaching a wallet with a free message signature turns it into a full SI Passport, whose tier comes from $SI, and keeps its stamps.
No. A passkey is enough: Face ID, a fingerprint, a screen lock or a security key. You can attach a wallet later.
You sign one free message with the wallet. If the wallet has no SI Passport, one is made. Your stamps and follows move to it, and your guest number retires.
Votes, checks, tiers and rewards belong to holders, read from the wallet. A Guest Passport has no wallet, so it never counts as a holder anywhere.
Many passkeys sync across your devices through your phone or computer account. If yours does not, make a new Guest Passport, or attach a wallet to keep your stamps for good.
No. Your device checks your face or fingerprint itself and only tells sicto.si that the passkey was used. No picture, print or code leaves it.
In browsers that support related origins it does, on all six. In other browsers it works on the site where you made it.
Join in a few seconds, collect the stamps, attach a wallet when you are ready.
Ask SI answers from the official site and live market data. It never asks for keys or seed phrases and gives no financial advice.
