How electronic signatures work in Capture
When you sign in Capture (a visit sign-off, a randomization, a change to a live study), you type your password again and confirm a stated meaning. Each signature records your name, the date and time, and what you approved. You accept a one-time acknowledgment that it equals your handwritten signature.
The one-time acknowledgment
The first time you open a study, Capture shows the Electronic Signature Acknowledgment. It explains that your electronic signature is the legal equivalent of your handwritten signature, that you are responsible for everything done under your account and must not share your password, and that all signatures are kept in a tamper-evident audit trail.
Read the statements.
Tick the box that you have read and agree to the declaration.
Click Accept and Continue.
Your acceptance is time-stamped once for your account; you are not asked again.
Signing with your password
Each signature dialog shows who is signing, the date and time, and the meaning of the signature, for example "Approved change" for a change to a live study. Type your sign-in password in the box (browsers and password managers will not fill it in for you) and confirm.
- Launching a study: "I authorise the launch of this study for enrolment and data collection."
- Changing a live study: you approve the change and confirm the reason given is accurate.
- Signing off a visit or casebook, randomizing, dispensing study drug and signing training all use the same password check.

Questions
Are Capture electronic signatures 21 CFR Part 11 compliant?
Yes. Signatures need your password at the moment of signing, carry a stated meaning, your printed name and the server time, and are kept in the audit trail. See our electronic signatures overview and the 21 CFR Part 11 checklist.
How do participants sign their consent?
