When you choose to link your device to another account, there are a few steps:
- On the device which has a Jami account, enter the account password and a PIN will be generated.
- When you click on “Link another device to this account”, the account will be sent on the DHT for 5 minutes and a PIN code is generated at this time.
- Generally, in Settings → Accounts → Choose your account → Link another device to this account
- Enter the PIN code on the other device.
