How often can access tokens be renewed in Vault?

Access tokens in Vault can be renewed as defined by their lease duration. This is a crucial aspect of Vault's security model, as it allows tokens to have a specific lifespan, after which they need to be renewed or replaced. The lease duration dictates how long a token remains valid, and renewal is typically possible at any point before the token expires, providing the system is configured to allow it.

This mechanism helps maintain a strong security posture by ensuring that access is regularly validated and that tokens do not remain valid indefinitely, which could present a risk if a token were to be compromised. Instead, the renewal process ensures that active sessions are still authorized and can adapt to changes in access needs or security policies over time.
