Room For Improvement

Featured Reviews

Senior Network and Security Engineer at Symbol Technologies PLC
Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
Vaibhav Patil - PeerSpot reviewer
Digital Marketer at DigiLiterate
Single sign-on has simplified daily logins and now secures all our marketing workflows
OneLogin by One Identity has many features available. These include Single Sign-On, Multi-Factor Authentication, centralized access control, instant onboarding and offboarding, and passwordless convenience. All of these features definitely help. I rely mostly on Single Sign-On in my day-to-day work with OneLogin by One Identity. It stands out because it removes the biggest daily headache: juggling passwords for every marketing tool. With SSO, I log in once and instantly access Google Ads, HubSpot, Looker, Meta Ads, Slack, and everything else. There are no password resets, no delays, and no asking IT for access. It saves time every single day and keeps my workflow smooth, especially when I'm switching between multiple dashboards and campaigns. One hidden gem feature in OneLogin by One Identity that often gets overlooked is context-aware or adaptive access control. With this, access isn't just on or off. Instead, OneLogin by One Identity can allow or restrict access depending on conditions, such as your location, IP address, device type, or time of day. For example, if you're logging in from an unknown location or public Wi-Fi, OneLogin by One Identity can automatically require stronger authentication. This adds a subtle but powerful layer of security without complicating day-to-day logins. It's ideal for remote work, travel, or working from shared spaces. Since implementing OneLogin by One Identity, the biggest positive change I've noticed is how much smoother and faster my workday feels. I no longer juggle multiple passwords or get stuck waiting for access to tools. Logging in once and instantly opening Google Ads, HubSpot, Looker, Slack, and everything else has easily saved me 15 to 20 minutes a day. Another major improvement is clean, consistent permissions. There are no more access denied issues or chasing IT for fixes. When someone joins or leaves the team, their access is handled automatically, which keeps everything secure and organized. Overall, OneLogin by One Identity has reduced small daily frustrations, improved security, and made my workflow far more efficient. Other impacts of OneLogin by One Identity include fewer IT tickets, faster onboarding, consistent access, higher security, less downtime, and better collaboration.
