How is 'OAuth' (the authorisation framework) pronounced?
OAuth is pronounced /ˈoʊ.ɔːθ/ — 'OH-awth', combining 'O' (the letter) with 'auth' (short for authorisation, rhyming with 'moth' or 'cloth'). Spelling it out as individual letters ('oh-ay-tee-aych') is never done in conversation. Saying 'OH-ath' (short 'a' as in 'cat') is a common mistake.
2 / 5
How is 'SAML' (Security Assertion Markup Language) pronounced?
SAML is pronounced /ˈsæm.əl/ — 'SAM-ul', like the male given name 'Samuel' but without the final syllable. Security professionals universally use this one-word pronunciation rather than spelling it out. The 'a' is a short vowel, not the long 'ay' of 'same'.

How is 'PKCE' (Proof Key for Code Exchange) pronounced?
PKCE is pronounced /ˈpɪk.siː/ — 'PIK-see', nicknamed 'pixie' by the OAuth working group. This informal but officially acknowledged nickname is used in conference talks and documentation. Spelling it out letter by letter ('pee-kay-see-ee') is technically understood but rarely used in speech.
4 / 5
How is 'FIDO2' (the passwordless authentication standard) pronounced?
FIDO2 is pronounced /ˈfiː.doʊ tuː/ — 'FEE-doh two', with a long 'ee' sound in the first syllable. FIDO stands for Fast IDentity Online and is said as a word (like the dog's name 'Fido'), but with the 'FI' as 'fee' rather than 'fy'. The '2' is simply 'two'.
5 / 5
How is 'mTLS' (mutual TLS authentication) pronounced?
mTLS is pronounced /ˌɛm.tiː.ɛl.ˈɛs/ — 'em-tee-el-ESS', spelling out each letter after the 'm' prefix. The 'm' stands for 'mutual' and is said as the letter 'em'. TLS is always spelled out, never said as a single word. Attempts to compress it into 'MIT-ilz' or similar are not standard.
