Preshared keys are saved as encrypted keys once you save the config and we cannot see the decrypted value. If you lost the key, the ideal option is to change the keys on both sides of tunnel.

You can see the encrypted keys in below location on GUI/CLI.

config vpn ipsec phase1-interface
edit "Test"
set interface "port3"
set peertype any
set net-device disable
set proposal aes128-sha256 aes256-sha256 aes128-sha1 aes256-sha1
set comments "VPN: Test (Created by VPN wizard)"
set wizard-type static-fortigate
set remote-gw 10.10.10.1
set psksecret ENC E/W7Rt2omWmzvZOX1qGGf7ice4JdqdsSxbPLfAkKGDV9tywVxPkHVFXZE9sszT75k7gdcdXldz5uTofF60OmMYdqHBxULCAAAbNLtZ/2DBecLwoEY5Q9a3NqNmU5ZDSsC7OClaCbeaTZMAPsN2ev+yAyBaxfw9stMMGDfx7Jdy+P/YBJyJ3BR+IxIRaWBsV4vvtUiw==

Hi @johnlloyd_13 

Hint:
as @srajeswaran mentioned, encrypted secret/pre-shared key is visible in CLI.
In case you would need to restore such config it is in there, in backup, or could be even copied and paste to new config and it will still work. If the opposite side of the VPN still has the same pre-shared key, then tunnel will work even without knowledge of actual plain text form.
