OAuth is an authorization protocol enabling a third-party application to access resources, such as data and content, from another resource provider system on behalf of a user. An OAuth Developer is a specialist who has the technical capabilities to facilitate the secure transfer of data from one system to another. OAuth Developers work with clients who want to enable their users to transfer data from one application to another, as well as enable access to external resources with out having to provide credentials.
Essentially, OAuth Developers are responsible for ensuring that the proper security measures are in place for this data transfer, and interoperate various components in order to make it all happen. OAuth Developers require extensive knowledge in backend technologies and security protocols.

De 19,178 opiniones, los clientes califican nuestro OAuth Developers 4.9 de un total de 5 estrellas.I already hold an X.509 digital certificate and I now need a matching set of JSON Web Key Sets (JWKS) built from it so I can feed the keys into an OAuth / OIDC gateway. The keys must be created for the RSA algorithm only; I do not require EC or HMAC variants at this stage. What I will hand over: • The existing X.509 certificate file (public and private parts available) along with any password that protects the private key. • Any metadata you need about issuer, key-use (sig), kid naming conventions, or expiry. What I expect back: • A correctly structured containing the public RSA key entries ready for direct publication. • The corresponding private key in a secure format of my choosing (PKCS#12 or PEM) and clear instructions on how it maps to the JWKS. • A ...
I run multiple WordPress sites and a React Native mobile app that should feel like one ecosystem. I need one secure sign-in that automatically works across all three properties and logs the user out everywhere when they choose to sign off. I’m open to your expert recommendation proposal—so long as the solution remains lightweight, secure, and easy for my team to maintain later. Here’s what success looks like: • A single authentication flow that lets a user log in on any of the WordPress sites or the app and arrive at the others already authenticated • Centralised session handling that survives token refreshes and password changes • A clean logout that invalidates sessions across every platform • Brief technical documentation explaining how to e...

My primary Gmail address has been disabled by Google for “suspicious activity.” The only specific clue Google gave me is that there were unusual login locations before the shutdown. I still own the recovery phone and backup email tied to the profile, but the standard appeal form has so far led nowhere. I’m looking for someone who already knows Google’s account-recovery and appeal workflow inside out—someone who can draft the right responses, supply any required logs or headers, and walk me through additional verification steps so the mailbox, Drive, Photos, and linked services come back online without data loss. Selected red-flag Google detected: • Unusual login locations Desired outcome • Full re-activation of the Gmail/Google account ...

I need a lightweight web page that lets my uncle and me create spray-job quotes without touching spreadsheets. All item data already lives in a Google Sheet that stores only the item name and its base price. The app must: • Authenticate visitors through Google OAuth and check the signed-in email against a simple whitelist I will maintain, so only approved addresses see the page. • Read item names and prices from the existing Sheet, present them in a friendly interface, let us enter quantities, then calculate the total with a variable, per-quantity rate (price × quantity, plus room for a small future formula tweak). • On submission, write the full quote—items, quantities, line totals, grand total, date, and the user’s email—to a separate “Qu...

I want Employment Hero talking seamlessly to our current HR management system so that staff information stays consistent everywhere. The scope covers three core workflows: employee onboarding, performance reviews, and leave management. Data from each of these modules needs to flow in real time, not on a scheduled batch, so webhooks or an always-on API connection will be essential. My HR platform already exposes REST endpoints and supports OAuth2. Employment Hero provides an open API as well, so the task is mainly about mapping fields, building the middleware (or configuring Zapier/Make if you feel it’s quicker), and validating that the sync runs bi-directionally without conflicts or duplicate records. Deliverables • Field-mapping document for all three modules • Worki...
