kredencial

Kredencial is a term used in several languages to refer to proof of identity or authorization. In general, a kredencial is something that ties a person or entity to a verified identity or granted privilege.

In information security and digital systems, credentials are the data that authenticate a user or device. Typical examples include usernames and passwords, PINs, security tokens, digital certificates, and biometric data. Credentials enable access to systems, services, or resources and are commonly protected with measures such as hashing, encryption, and multi-factor authentication.

In non-digital contexts, kredencial can denote official documents or certificates that prove qualifications or status, such as diplomas, licenses, professional certifications, or membership cards. These credentials may be required to enter workplaces, participate in certain activities, or prove eligibility.

Spelling variations exist across languages. English uses credential; in many Romance languages the form credencial is common, while some languages spell it with a leading k (for example kredensial or kredencial in certain contexts). The concept is closely related to digital identity, access control, and credential management.

Common issues include credential theft or leakage, phishing, and credential stuffing; organizations implement practices like MFA, least privilege, and secure storage to mitigate risks.
