# Sign as a signed-in user
When you are invited to sign a document, you will receive a notification in your email.
If you are signed in to the SignSpace service, the **View signature request** link will direct you to the SignSpace application.
To start the signing process, click on **Read and sign** next to your name, which will open a preview window of the document.
Read all documents - there may be one or more documents. Document preview may not be available for all document types. In this case, the files must be downloaded to a computer for reading.
If you are not the right person to sign the files in question, or if changes need to be made to the files, you have two options depending on the settings defined by the inviter:
* [Delegate signing](https://signspace.zendesk.com/hc/en-gb/articles/11297144780562)
* [Refuse to sign](https://guide.signspace.com/en/signing/decline-to-sign)
If you are the right person to sign, click the **Sign 1 document now** button after reviewing all documents.
When the signature level **Light** has been selected for the signature request in the creation phase, strong electronic identification is not required.
If the signature level is set to **Strong**, signing requires strong electronic identification.
For more information about signature levels, see [Learn about alternative signing levels](https://guide.signspace.com/en/managing-signing-requests/learn-about-alternative-signature-levels)
After successful authentication, you will receive a notification that the signing was successful and return to the signature request view.
For your name, the signing status has changed to **Signed**.
**Note!** If you are not the last signatory of the document, your electronic signature will not yet appear in the document attached to the signature request. The document's signatures only become visible when all signatories have signed it. You will receive an email when all signatories have signed the document and the documents with electronic signatures are attached / ready for download.
