Different problems, different tools
A password manager is a vault: long-term storage for credentials you use repeatedly. A one-time secret link is a courier: short-term delivery of a credential to someone who does not have your vault.
The mistake teams make is using one tool for both jobs. Sharing a vault entry by emailing an exported file defeats the vault. Storing every contractor password forever because the courier link was convenient creates a growing pile of stale secrets.
Use the courier for handoffs
When someone needs a credential once, a self-destructing secret link is the cleaner path. The recipient gets exactly what they need, the ciphertext deletes itself after reading, and nothing accumulates in either party's records. No shared vault, no guest accounts, no license seats for people who needed one password one time.
Use the vault for everything ongoing, and reserve one-time links for the moment of transfer. The two tools complement each other: the vault reduces how often secrets need to travel, and the courier makes each trip as small and brief as possible.
