Step 6: Position Your Signature
Place your digital signature on the document where you want it to appear. Most tools allow you to drag and drop the signature to the desired location.
Step 7: Adjust Signature Size and Style
You can often resize or adjust the appearance of your digital signature to make it fit perfectly on the document. Ensure that it looks neat and proportional.
Step 8: Save the Signed Document
After adding your digital signature, save the document. The signing tool will usually create a digital fingerprint of the document along with your signature to ensure its integrity.
Step 9: Verify the Signature
Many digital signing tools provide a verification feature that lets you confirm that the digital signature is valid and has not been tampered with. This a very useful feature, it may be used to ensure the authenticity of the signed document.
Step 10: Share or Store the Document
Now that your document is digitally signed, you can share it electronically with others or store it securely. Digital signatures are legally recognized in many contexts, so your digitally signed document holds the same weight as a physically signed one.
Tips for Creating a Unique and Secure Digital Signature
Follow these best practices when making your digital signature:
- Incorporate Stylistic Elements: Add flourishes and personal touches just like a handwritten signature.
- Make It Difficult to Duplicate: Use varied line weights, colors, sizes, and complex styles.
- Update Periodically: Change your signature occasionally to prevent prolonged forgery risks.

Alternatives to Digital Signatures
It’s important to note that the alternatives mentioned below might have varying levels of legality, security, and acceptance depending on the context and jurisdiction. Digital signatures, due to their cryptographic nature and legal recognition in many places, often provide a more secure and widely accepted solution for electronic document signing.
Here are some alternatives to digital signatures:
Electronic Signatures:
Electronic signatures are a broader category that includes digital signatures but also encompasses various methods of indicating agreement electronically. These can include checkboxes, typed names, or even a simple “I agree” button.
Handwritten Signatures:
Scanning or photographing a handwritten signature and adding it to a digital document is a simple way to create a personal touch, but it may not provide the same level of security and non-repudiation as digital signatures.
Biometric Signatures:
Some unique physical characteristics like fingerprints, facial recognition, iris, or voice patterns are used in Biometric signatures to confirm identity and provide a level of security similar to digital signatures.
Blockchain Technology:
Blockchain offers a distributed and immutable method for documenting transactions and contracts. While distinct from a traditional signature, the cryptographic methods inherent to blockchain can be harnessed to establish credibility and unanimity.
Two-Factor Authentication (2FA):
In addition to a regular signature, 2FA involves another layer of verification, such as receiving a code on your phone or email, which adds an extra level of security to the signing process.
Timestamps and Certificates:
Using a trusted timestamping service, you can record the exact time when a document was signed, providing evidence of the document’s state at a particular time. Certificates can also be used to validate the signer’s identity.
DocuSign and Similar Platforms:
Online platforms like DocuSign offer a digital way to request signatures, guiding signers through the process and storing documents securely in the cloud.
Smart Contracts:
In the context of blockchain, smart contracts are self-executing contracts with the terms of the agreement written directly into code. They can automate and validate processes without the need for traditional signatures.
Consent Buttons or Checkboxes:
For simple agreements, especially in online contexts, consent buttons or checkboxes can indicate agreement to terms or conditions.
Email Confirmation:
In some cases, confirming agreement via email response can serve as a form of digital confirmation, though it might be considered less secure.
