Register a digital ID
To use your digital ID, register your ID with Acrobat or Reader.

2 Select Digital IDs on the left.
3 Click the Add ID button .
4 Choose one of the following options:
A File Select this option if you obtained a digital ID as an electronic file. Follow the prompts to select the digital ID
file, type your password, and add the digital ID to the list.
A Roaming Digital ID Stored On A Server Select this option to use a digital ID that’s stored on a signing server. When
prompted, type the server name and URL where the roaming ID is located.
A Device Connected To This Computer Select this option if you have a security token or hardware token connected
to your computer.
5 Click Next, and follow the onscreen instructions to register your digital ID.
Specify the default digital ID
To avoid being prompted to select a digital ID each time your sign or certify a PDF, you can select a default digital ID.
1 Select Preferences > Signatures. In Identities & Trusted Certificates, and click More.
2 Click Digital IDs on the left, and then select the digital ID you want to use as the default.
3 Click the Usage Options button , and choose a task for which you want the digital ID as the default. To specify
the digital ID as the default for two tasks, click the Usage Options button again and select a second option.
A check mark appears next to selected options. If you select only the signing option, the Sign icon appears next
to the digital ID. If you select only the encryption option, the Lock icon appears. If you select only the certifying
option, or if you select the signing and certifying options, the Blue Ribbon icon appears.
To clear a default digital ID, repeat these steps, and deselect the usage options you selected.
Change the password and timeout for a digital ID
Passwords and timeouts can be set for PKCS #12 IDs. If the PKCS #12 ID contains multiple IDs, configure the password
and timeout at the file level.
Note: Self-signed digital IDs expire in five years. After the expiration date, you can use the ID to open, but not sign or
encrypt, a document.
1 Select Preferences > Signatures. In Identities & Trusted Certificates, and click More.
2 Expand Digital IDs on the left, select Digital ID Files, and then select a digital ID on the right.
3 Click Change Password. Type the old password and a new password. For each keystroke, the password strength
meter evaluates your password and indicates the password strength using color patterns. Confirm the new
password, and then click OK.
4 With the ID still selected, click the Password Timeout button.
5 Specify how often you want to be prompted for a password:
Always Prompts you each time you use the digital ID.
