deploy on shinyapps.io ERROR shinymanager

This its my firts question in the ghroup so hope to be clear.
I cant deploy a dashboard in shinyapps adding shinymanager and keyring; when run it in local desktop works fine, but when deploy to shinyapps: display the security screen; type de user and password and the server cut out the sesion and logout asking to reload .

the logs in shinyapp show the error :

Warning in default_backend_auto() :
** Selecting ‘env’ backend. Secrets are stored in environment variables**
** Warning: Error in b_env_get: Cannot find password**
13: runApp
12: fn
** 5: eval**
** 7: connect$retry**
