@1voud I unlocked @johndi89 in a call it was an issue with the jwt keys permissions.  
So first you need to check the ownership of the jwt folder:

```auto
sudo chown -Rf root:www-data /etc/passbolt/jwt
sudo chmod 750 /etc/passbolt/jwt
sudo chmod 640 /etc/passbolt/jwt/jwt.key
sudo chmod 640 /etc/passbolt/jwt/jwt.pem

```

Then logout from your account  
Login again  
Try to transfert the key again on mobile  
If there is still an issue we can try:

```auto
sudo /usr/share/php/passbolt/bin/cake passbolt create_jwt_keys -v -f

```

Then like before, logout, login, transfert on mobile

Let me know
