The library functions from your own C-program would be: 1. Esys_GetCapabilities() / Tss2_Sys_GetCapabilities() with parameters capability = TPM2_CAP_TPM_PROPERTIES property one of: - TPM2_PT_LOCKOUT_COUNTER - TPM2_PT_MAX_AUTH_FAIL - TPM2_PT_LOCKOUT_INTERVAL - TPM2_PT_LOCKOUT_RECOVERY 2. Esys_DictionaryAttackLockReset() / Tss2_Sys_DictionaryAttackLockReset() or from bash using tpm2-tools: $ tpm2_getcap --capability=properties-variable search for TPM2_PT_LOCKOUT_COUNTER, TPM2_PT_MAX_AUTH_FAIL, TPM2_PT_LOCKOUT_INTERVAL, TPM2_PT_LOCKOUT_RECOVERY $ tpm2_dictionarylockout --clear-lockout Hope this help...
