Alert message login

I having difficults to pass this problem here
soon as ithe robot enter this page
shows this message

I tried this on my code
${auth}= Create Dictionary username=${hidden_user} password=${hidden_pass}
Create session alias=Get_HCPA_Request url=${link} auth=${auth}

    # Sleep    3s
    # Type Letters Separately     abcdef123
    # Press Keys    None    Tab
    # Type Letters Separately    abcdef123
    # Press Keys    None    Enter
    Wait Until Page Contains   Password
    Input Text    id=username     abcdef123
    Input Password    id=password    abcdef123
    Submit Form

the Create session did completed sucessfully but I believe when he opens the browser it’s not same session.

Does anyone know anyway to pass this problem ?
