how to set ttl in keycloak admin console?

[garypan1990]

HI,
I would like to know how to set the TTL in the Keycloak admin console because I am using email OTP authentication. I received an email containing the code, but it does not show the TTL as depicted in the attached picture.

keycloak version: 21.1.0

Thank you.

You can set the TTL (and other parameters) directly from the Keycloak admin console under your authentication flow configuration.

Go to Authentication → your flow → Email OTP execution → gear icon (⚙) → Config and you will see fields like:

• Time-to-Live (seconds) — how long the code is valid (default: 300 s = 5 minutes)
• Code Length — number of digits (default: 6)
• Resend Cooldown (seconds) — wait time before a new code can be requested

Note: version 21.1.0 is very old and may not have all these config fields. The current release is v26.3.1, which supports Keycloak 26.5.x – 26.6.x. Please upgrade to a supported version for the full feature set.
