We only list products in this section that have a third party security audit, (with the exception local password managers). I couldn’t find anything about that for this particular product.
In fact all I was able to find was aggressive marketing campaigns (astro turfing), saying the product was secure, and an article entitled “Security Audit” which was about auditing users in your team, not a third party security audit. I suspect they purposely chose to name that page, that in order to achieve certain search engine results.
In the case of Bitwarden and 1Password these have had regular audits:
This is why we require third party security audits. As for LastPass that was known to be bad for quite some time, sadly people just believed the marketing, and used it anyway.
