# Time Stamp Settings

Signature with an embedded timestamp and certificate status information is referred to as a Long Term Validity (LTV) signature. Long-term digital signatures are essential if the signed documents need to be verified months or years later.

LTV (Long Term Validity) Settings allows you to configure Time Stamp Authority (TSA) credentials, so that the timestamp is fetched from TSA while signature is placed in the document.

**Step 1:** Login to emSigner Super Admin account. Click on ‘Settings’ tab to open the Admin Settings. Click on ‘***Timestamp Settings***’ below Admin Settings

* Time Stamping URL  – enter the Time Stamp Authority (TSA) URL in the text field
* Time Stamping User Name – select “Time Stamping User Name” and enter the user name if any provided by TSA
* Time Stamping Password – enter the password if any provided by TSA

Once the above configurations are performed by the administrator, while performing electronic signatures by the signatories, signatures will be certified and time stamped by the Time Stamping Authority. This signature can be verified even months or years later.
