A Password Generator Built for Indian Banking, UPI, and Government Portals

India's digital public infrastructure has scaled faster than its password hygiene. Between UPI, net banking, IRCTC, Aadhaar-linked services, income tax e-filing, EPFO, and a work email, a single user easily juggles a dozen credentials — and many still default to names, birthdays, or the same reused string across portals. When we built the password generator at FreeOnline.fyi, the goal was not novelty. It was to give someone on a mid-range Android phone a trustworthy, offline-capable way to make a strong password in under thirty seconds, with no app install and no account creation.
The reality for most Indian users is that they need this on demand. A new bank account gets opened, a UPI pin expires, an income-tax e-filing password needs rotating after a year, and a DigiLocker session asks you to re-verify. Each of those moments is a small decision point where convenience wins over security, and the user ends up reusing a variation of an old password. A tool that produces a strong, memorable candidate without forcing them to leave the browser closes that gap.
The interface is intentionally flat.
The interface is intentionally flat. You drag a length slider that runs from 6 to 64 characters, tick which character classes you want — uppercase, lowercase, digits, symbols — and optionally flip a switch to exclude visually ambiguous characters like l, 1, I, O, and 0. We default the length to 16 because most Indian banking portals comfortably accept that range, and we default ambiguous-character exclusion on because mistyped passwords are a silent source of login failures on cramped mobile keyboards.
There are also two smaller but useful fields. A free-text box lets you strip specific characters — useful if a portal rejects quotes or backslashes in passwords. A "must include" box guarantees that a substring, such as your initials, appears in every candidate. We added these after noticing how often users bounce between banking sites with subtly different password policies, and how a quick fix in the generator saves three failed attempts and a password reset.

Below the controls sits a prominent Generate button, and beneath that a list of up to twenty candidates. Each row is masked by default and reveals with a tap on the eye icon; a tap on the row itself copies the password to the clipboard with a two-second toast confirmation. On older mobile browsers that block programmatic clipboard access, we fall back to a long-press prompt so the workflow still completes.
The strength meter isn't decoration. Each candidate ships with a coloured bar, a numeric entropy figure in bits, and an estimated crack time at typical offline attack speeds. The meter is calculated from the actual search space the user chose, not from a vibes-based heuristic, so a 12-character all-lowercase password correctly shows as weaker than a 16-character mixed-symbol one even when both look similar on screen. We've seen users gravitating toward the excellent tier and then complaining the resulting string is impossible to type — which is exactly the trade-off the meter is meant to surface.

If you want to read the formal guidance behind these choices, the NIST SP 800-63B Digital Identity Guidelines recommend a minimum of eight characters with no mandatory composition rules, but they place real weight on length and on screening against commonly used or breached passwords. Our defaults err conservative on length because length is the single most leverageable variable in entropy.
The most common workflow we've observed is rotating a banking password every few months. A close second is generating a strong master password for a password manager the user already trusts. We've also watched people use the tool for one-off KYC verifications on lesser-known apps, where you don't want your primary email password exposed if the vendor gets breached a year later. For users who want to keep generated passwords somewhere durable before they get into a real vault, pairing the generator with our image to PDF converter is a low-tech but effective way to screenshot and archive a small batch of freshly minted credentials.

A pattern we did not anticipate but quickly came to appreciate is generation for family members. A parent on a feature-phone-adjacent Android handset, asking their child to set up a strong password for their SBI or Canara net banking account, is now a routine user story in our testing. The slider, the toggles, and the eye icon all read well at 360 pixels wide, which is not a given for security tools.
Finally, several readers use the generator to create a one-off login for a government scheme portal that they only intend to visit twice. In that case the password really is single-use, and a strong random string from the generator is genuinely fit for purpose — no manager needed, just a copy, a paste, and a logout.
Everything runs locally in the browser.
Everything runs locally in the browser. We do not transmit generated passwords anywhere — there is nothing to leak because nothing leaves the page. We also do not store history, so closing the tab genuinely wipes the candidates. This is worth being explicit about, because it cuts both ways: if you refresh before copying, the passwords are gone for good. We considered adding a download-as-file option and held off, because a plaintext file on your desktop is itself a risk. If you need persistent storage, use a reputable password manager; if you only need one strong string right now, the generator is enough.
It also runs without tracking, without cookies, and without an account. You can open it from a private tab on a borrowed device and leave no trace. For a tool that touches credentials, that property matters more than any feature list, and it's part of why we chose to keep it on a static page rather than behind a login.

The strength meter assumes an attacker is running offline brute-force hardware at consumer GPU speeds. A nation-state adversary, or a service with no rate limiting on login attempts, will behave differently. Also, no password — however strong — protects an account whose underlying service has been breached. For that layer of risk, CERT-In's advisories are worth bookmarking; they publish vulnerability notes and incident guidance specific to the Indian context, which general-purpose security blogs rarely cover.
Two practical tips from our own use of the tool. First, rotate banking and UPI passwords every three to six months, and never reuse one across net banking and a social login — the blast radius of a leak on a low-value site should not reach your savings account. Second, treat the generator as the front half of a workflow, not the whole thing: generate, copy into a password manager, and let the manager's autofill handle the typing from then on. The tool does one job well; combine it with good storage habits and you close most of the realistic attack surface that everyday Indian internet users face.
