When Chrome won’t let you sign in (or it signs you in and immediately kicks you back out), it’s usually a cookie/session problem or a Chrome profile issue—not your password.
Work through the steps below in order; they go from “quick and reversible” to “deeper reset.”
1. Confirm it’s not the site (quick cross-check)
Before changing Chrome settings, check whether the login issue is specific to one site.
- Try signing in on the same site using an Incognito window.
- Try the same account on another browser (Edge, Firefox) or another device.
- If the site shows a status page or outage notice, check it.
If it works elsewhere but not in regular Chrome, the next steps will usually fix it.
2. Turn off extensions (especially ad/privacy tools) and try again
Extensions that block trackers, scripts, pop-ups, or cookies can break modern sign-in flows—particularly “Continue with Google/Apple/Microsoft.”
- Open Chrome’s extensions list and temporarily disable them all.
- Retry the login in a normal (non-Incognito) window.
- If it works, re-enable extensions one by one to find the culprit.
Common offenders: ad blockers, anti-tracking, script blockers, VPN/proxy extensions, and “cookie cleaner” add-ons.
3. Check cookie settings (third‑party cookies often cause the loop)
Many logins rely on a separate identity domain setting cookies (for example, a “sign in with…” provider). If third‑party cookies are blocked, you can get an endless redirect or instant logout.
- In Chrome settings, verify you’re not blocking cookies globally.
- If you block third‑party cookies, add an exception for the site you’re using and its sign-in provider.
- Also check for “clear cookies on exit” behavior (either in Chrome settings or an extension).
A good test: if Incognito works but normal Chrome does not, cookie/storage rules are very likely involved.
4. Clear cookies for just that site (not your whole browser)
If a site’s session cookie is corrupted or out of sync, clearing only that site’s stored data is usually enough (and won’t log you out everywhere).
- Open the affected website.
- Clear site data (cookies + storage) for that domain.
- Close the tab, reopen it, then sign in again.
This is one of the fastest fixes for “logs me out immediately after login.”
5. Allow pop-ups and redirects for the login page
Some sign-in flows open a small authorization window or rely on redirects that can look like pop-ups.
- Temporarily allow pop-ups/redirects for the site you’re signing into.
- Retry the login, then you can tighten the setting again after.
If you see a brief flash of a new window that instantly closes, this step is especially relevant.
6. Check date/time and your network (VPN, proxy, captive Wi‑Fi)
Incorrect device time or “intercepted” networks can break secure session creation (cookies, tokens, and TLS checks).
- Set your device time to automatic (correct time zone too).
- If you’re on public Wi‑Fi, open a new tab and confirm you’re not stuck behind a captive portal login.
- Disable VPN/proxy temporarily and retry.
It’s a boring fix, but it catches a surprising number of sign-in failures.
7. Create a fresh Chrome profile (best fix for persistent sign-in weirdness)
If nothing above helps, your Chrome profile may have corrupted local storage, broken preferences, or a bad cached identity state.
- Create a new Chrome profile (separate from your current one).
- Try signing into the website from the new profile before installing extensions.
- If it works, migrate gradually: bookmarks first, then add extensions carefully.
If you rely on Chrome Sync, sign in to Sync after you confirm web logins are stable in the new profile.
Final thoughts
Most Chrome login loops come down to cookies (especially third‑party cookie rules) or extensions that quietly block part of the sign-in flow.
If you want the quickest “proof,” try Incognito (no extensions by default) and then fix the specific cookie/extension setting in your normal profile.
