For companies that are already using other Atlassian systems, then Atlassian Crowd will fit in very well. This is especially the case if the company is not yet big enough to use LDAP for user management, Atlassian Crowd can act as a temporary solution until the company outgrows it, as it is much easier and simpler than LDAP.
Bitwarden supports various forms of two-factor authentication, including time-based one-time passwords (TOTP), Duo, YubiKey, and other hardware-based tokens. This integration enhances the security of the Bitwarden account and allows to store and manage their 2FA credentials for other applications within Bitwarden itself.
Easy to use, just missing a few quality of life features. Nothing to suggest it's not awesome as it is, just bells and whistles to make it more convenient.
Overall, support is good, you get quick responses from Atlassian's official support system, and documentation is decent enough for you to find what you need.
These products allow you to install them on your own infrastructure, so you can manage all aspects of them which can prevent you from getting throttled from API calls. When you hit a certain threshold of scale you may need to switch off of Atlassian Cloud to your own hardware. When you are a small startup, however, this product is probably a good starting point.
Other solutions felt more clunky or were significantly higher priced. Bitwarden seems to straddle the consumer/prosumer/SMB fence more than adequately by designing their user experience to feel welcoming but also trustworthy and reliable. The other tools seem to assume that users are ok with struggling in their onboarding process.
New systems are tough when it comes to an ROI, as a dollar amount for saving time on a sign-in can be tough to track. Like most new systems that makes things slightly easier to execute as an end user or manage or support, it really might come down to the existing structure of how a company manages its users.
The positives are always with the end user, which I have to say, Crowd was able to accomplish.
