Recent changes to Chrome could affect your agency. Chrome now requires that TLS/SSL certificates issued on or after **March 1, 2018**, have a maximum lifetime of 825 days. Google is enforcing this change for Chrome as a result of the Certification Authority/Browser (CA/B) Forum's Ballot 193 to promote increased web security.<sup>[1](#1)</sup> | ||
|
||
## What Will Be Impacted? | ||
A government user will receive an "untrusted site" error when browsing to an intranet website or application if all of the following are true: | ||
|
||
1. The intranet website's TLS/SSL certificate was issued by a Federal PKI Certification Authority | ||
2. The TLS/SSL certificate was issued on or after March 1, 2018, with a lifetime greater than 825 days | ||
3. Using the Chrome browser | ||

|
||
## What Other Browsers Enforce This Requirement? | ||
Chrome is the only browser currently enforcing this requirement for TLS/SSL certificates. If other browser vendors decide to enforce this requirement, we will post updates to this announcement. Please also check the [FPKI-Guides' Issues](https://github.com/GSA/fpki-guides/issues){:target="_blank"}{:rel="noopener noreferrer"}{:class="usa-link usa-link--external"} for in-progress discussions. | ||
|
||
## What Should I Do? | ||
To prevent Chrome browsing errors: | ||
1. Request that your PKI team or Federal Shared Service Provider update the certificate profiles for TLS/SSL device certificates issued by Federal PKI Certification Authorities to require a certificate lifetime of less than 825 days. | ||
2. Re-issue and re-install new TLS/SSL certificates for the impacted intranet websites and applications. | ||

In March 2017, the [CA/B Forum](https://cabforum.org/){:target="_blank"}{:rel="noopener noreferrer"}{:class="usa-link usa-link--external"} passed [Ballot 193](https://cabforum.org/2017/03/17/ballot-193-825-day-certificate-lifetimes/){:target="_blank"}{:rel="noopener noreferrer"}{:class="usa-link usa-link--external"}, which introduced the 825-day maximum lifetime requirement. |
