  • receiving one-time password (OTP) data for validating one or more connectivity checks for establishing a media session, the OTP data including a sequencing function;

    determining a set of passkeys by applying the sequencing function to a seed value to acquire a first passkey and successively applying the sequencing function to a latest passkey to acquire one or more additional passkeys;

    sending at least one of an offer or an answer to an endpoint for establishing the media session, at least one of the offer or the answer including a first username that includes a passkey from the set of passkeys and a successive passkey from the set of passkeys;

    receiving a request for a connectivity check from the endpoint for establishing the media session, the request including a second username that includes the passkey and the successive passkey; and

    validating the second username based at least in part by applying the sequencing function to the passkey included in the second username to acquire a computed value and comparing the computed value to the successive passkey included in the second username.
