What is a passphrase？
A passphrase is some contextual information that also serves as a link for accessing certain areas of a system.
How to share and join groups via passphrase?
Go to Settings - Share and select share group link.
Click on Link and you can see a short paragraph that includes the group link. This paragraph is the group passphrase.
Copy the group passphrase and share it to others whom you would like to invite. The invited users can copy the passphrase and then open Feishu to join the group.
Notes:
- •The group owner must have enabled: Group members can share group in Group Settings, before other group members can invite others.
- •If the invited member is not a Feishu user, they will need to download Feishu app first and register before joining the Feishu group.
