Certificate attestation is the procedure used to validate a digital certificate's validity and authenticity and grant the certificate holder access to a certain website. A certificate can be attested in a number of ways, such as by using an online portal service or by requesting an email with a link that can be clicked to generate an attestation form that requires your input. Any document's legitimacy, especially a degree certificate, can be confirmed through a procedure called certificate attestation. The performer's experience, the organisation to which he belongs, and the training and qualifications he possesses are just a few of the many factors that go into the attestation procedure.
