HTTPS provides a secure, encrypted connection between { -brand-short-name } and the websites you visit. Most websites support HTTPS, and if HTTPS-Only Mode is enabled, then { -brand-short-name } will upgrade all connections to HTTPS.
Mae HTTPS yn darparu cysylltiad diogel, wedi'i amgryptio rhwng  { -brand-short-name } a'r gwefannau rydych chi'n ymweld â nhw. Mae'r mwyafrif o wefannau yn cefnogi HTTPS, ac os yw Modd HTTPS-yn-Unig wedi'i alluogi, yna bydd { -brand-short-name } yn uwchraddio'r holl gysylltiadau â HTTPS.
