How to Change the Expiration Period of an Acrobat Digital ID
Question details
The user needs a self-signed digital certificate in Adobe Acrobat to expire within three years, but the software applies a default expiration period.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Customizing the validity period of a self-signed digital certificate for document signing.
- Observed behavior
- Acrobat's self-signed certificates are generated with a fixed default expiration date, and the software does not provide a direct setting to shorten or modify this period after creation.
Keep in mind that once a digital ID is generated, its expiration date is cryptographically embedded and cannot be altered. You will need to create or purchase a new certificate to enforce a different validity period.
Obtain a New Certificate from a Certificate Authority (CA)
Since self-signed certificates in Acrobat cannot have their dates customized post-creation, the most reliable method for strict validity periods is obtaining a certificate from a trusted CA.
Acrobat's built-in self-signed digital IDs use a fixed default expiration (usually 5 years). It does not provide an interface to customize this duration during or after creation. For compliance requirements, such as needing a strict 3-year expiration, using a third-party Certificate Authority is the standard approach.
Choose a recognized Certificate Authority (CA) that issues document signing certificates.
During the purchase or generation process on the CA's platform, select your desired 3-year expiration period.
In Adobe Acrobat, go to Edit > Preferences > Signatures. Under 'Identities & Trusted Certificates', click 'More...', then use the 'Add ID' button to import your newly acquired digital ID file.
Generate a New Self-Signed Digital ID (With Default Expiry)
If you do not want to use a third-party CA and are willing to accept the default expiration period, you must generate a brand new self-signed ID.

Frequently Asked Questions
Why can't I edit the expiration date of my current Acrobat self-signed certificate?
Once a digital certificate is created, its cryptographic properties, including the expiration date, are permanently sealed. Allowing modifications to an existing certificate would compromise its security and validity.
What is the default expiration period for an Acrobat self-signed ID?
By default, Adobe Acrobat creates self-signed digital IDs with a validity period of 5 years from the date of creation.
Will my previous signatures become invalid when my digital ID expires?
Signatures applied before the certificate expired generally remain valid as long as the document has not been altered, because a timestamp is securely embedded at the exact time of signing.
How do I delete an expired digital ID in Acrobat?
Go to Edit > Preferences > Signatures > Identities & Trusted Certificates, select 'Digital IDs', choose the expired ID from the list, and click 'Remove ID'. You will need to provide your password to confirm the deletion.
