A word or phrase to describe documents that can expire

Question

I'm looking for word or phrase that describes documents or credentials that by definition have an expiry date. Examples of such documents can be:

• Passports
• Certifications
• Licenses
• Credentials

Answer 1

While I can find no authority to support these, the terms time-limited and time-restricted seem to logically (and semantically) apply.

If you want a colloquial phrase, consider good through (or thru) and good until as adjectival phrases.

Answer 2

• Transient-lasting only for a short time, (temporary)
• Transitory-not permanent
• Temporary
